Northrop to Complete Microwave Sounder for NASA
Northrop Grumman Corp. of Falls Church, Virginia, will build and deliver the Advanced Technology Microwave Sounder (ATMS) for the Joint Polar Satellite Systems (JPSS) under a contract with NASA.
JPSS is a system of polar-orbiting satellites to be developed by NASA for the National Oceanic and Atmospheric Administration (NOAA) for weather forecasting, storm tracking and climate monitoring.
The ATMS instrument is the second flight model and is slated to fly on the first JPSS satellite in 2016. The first ATMS was completed in 2005 and has been integrated on the NPOESS Preparatory Project (NPP) satellite, which is scheduled to launch in October.
ATMS will provide critical microwave data, including atmospheric temperature and moisture profiles, to support weather forecasting for the operational JPSS system. The instrument has 22 channels spanning the frequency band from 23.8GHz to 183.3GHz. It was designed to be the functional equivalent follow-on to the Advanced Microwave Sounder Units with improved sampling and coverage.
U.S. Army Awards Contract for OWL Radar
The U.S. Army’s Intelligence and Information Warfare Directorate has awarded SRC, Inc. of Syracuse, New York, formerly Syracuse Research Corp., a $500,000 phase one development contract for an Omni-Directional Weapon Location (OWL) radar system.

NIST on Electromagnetic Momentum Density Debate
Researchers from the NIST Center for Nanoscale Science and Technology and the University of British Columbia have shown that the interaction between a light pulse and a light-absorbing object, including the momentum transfer and resulting movement of the object, can be calculated for any positive index of refraction using a few, well-established physical principles combined with a new model for mass transfer from light to matter. This work creates a foundation for understanding light absorption in metamaterials, artificially tailored materials of intense interest in nanophotonics and microwave engineering that can have negative indices of refraction, and have potential applications in high resolution imaging, lithography, optical sensing, high gain antennas, and stealth radar coatings.
The researchers propose a set of postulates for light-matter interaction that encompass: The Maxwell equations, which govern classical electromagnetic behavior; A generalized Lorentz force law, which describes the force felt by matter in the presence of an electromagnetic field; A model for electromagnetic mass density transfer to an absorbing medium; and the Abraham formulation of momentum density. Using both closed-form calculations and numerical simulations of the interaction between an electromagnetic pulse and a test slab, the researchers demonstrated that their postulates yield results that are consistent with conservation of energy, mass, momentum, and center-of-mass velocity at all times. They further showed that satisfaction of the last two conservation laws unambiguously identifies the Abraham form as the true form of momentum density in a positive-index medium.

China Mobile Tests TD-LTE With T&M Equipment
China Mobile uses the R&S CMW500 in its Research Institute labs to perform RF tests on user equipment for time division LTE (TD-LTE). China Mobile plays a leading role in TD-LTE, the Chinese 4G mobile radio standard that succeeds TD-SCDMA, the Chinese 3G standard.
The R&S CMW500 from Rohde & Schwarz, a leading manufacturer of LTE test and measurement equipment, is a reliable, extremely fast and highly flexible wideband radio communications tester that supports all common wireless communications standards in a single box. It is the ideal solution for all phases in the development and production of chipsets and mobile wireless devices as well as for lab tests by network operators.
The China Mobile Research Institute performs measurements both in the lab and under real-world conditions. Since the beginning of 2011, it has already implemented TD-LTE test networks in six major cities: Shanghai, Hangzhou, Nanjing, Guangzhou, Shenzhen and Xiamen. Commercial operation starts this year.

Hopes Rise for Electromagnetic Cancer Treatment

Scientists have used low-intensity electromagnetic fields to treat cancer patients in trials which they say could lead to the development of a new type of anti-tumor therapy.
Patients hold a spoon-shaped antenna in their mouths to deliver a very low-intensity electromagnetic field in their bodies. In trials of patients with advanced liver cancer, the therapy – given three times a day – resulted in long-term survival for a small number of those monitored, the team has reported in the British Journal of Cancer. Their tumours shrank, while healthy cells in surrounding tissue were unaffected.
However, the scientists – from the U.S., Brazil, France and Switzerland – also stressed that the technique was still in its infancy and would require several years for further trials to take place. “This is a truly novel technique,” said the team’s leader, Professor Boris Pasche of the University of Alabama, Birmingham. “It is innocuous, can be tolerated for long periods of time, and could be used in combination with other therapies.”
Pasche stressed that the intensity of the fields used in his team’s experiments were between 100 and 1,000 times lower than those from a mobile phone.
Electromagnetic Waves for Medical Scanning
A breakthrough in exploiting electromagnetic waves has potentially opened the way for future terahertz waves (T-rays) systems to be smaller, more portable, easier to operate, and much cheaper than current devices, for medical diagnostics.
T-rays are already in use in airport security scanners, prototype medical scanning devices and in spectroscopy systems for materials analysis.
They can also sense molecules such as those present in cancerous tumors and living DNA, since every molecule has its unique signature in the THz range, the journal Nature Photonics reports.
The researchers say their more efficient continuous wave T-rays, the technology behind full body scanners, could be used to make better medical scanning gadgets, similar to the ‘tricorder’ scanner used in Star Trek.
Current T-ray imaging devices are very expensive and operate at only a low output power, since creating the waves consumes large amounts of energy and needs to take place at very low temperatures.
Materials science researchers have made T-rays into a much stronger directional beam than was previously thought possible, at room-temperature conditions.
Veran Ships SPiN Drive® Platform to Customers
Veran Medical Technologies of St. Louis, Missouri, has started shipping its SPiN Drive® electromagnetic navigation platform, an advanced solution that biopsies peripheral Solitary Pulmonary Nodules (SPNs) for the potential early diagnosis of lung cancer.
The SPiN Drive system design may improve efficiency and enhance workflow by allowing the physician to never lose or remove navigation at the time of biopsy with the Always-On Tip Tracked™ instruments. The platform is the first in electromagnetic navigation to provide optimal facility flexibility by requiring no unique bed or room calibration. Additionally, the ability to view airways during procedures may provide a significant advantage toward targeting SPNs.
Targets are viewed on high resolution CT images using a patient-specific view, without any radiation being delivered to the patient, physician or staff. In addition, the SPiN Drive technology includes bi-planar virtual fluoroscopy view used to navigate multiple planes simultaneously.
