A team of scientists from the University of California, San Diego (UCSD) have developed a material that resembles an invisibility cloak. The material could change the face of military operations and would allow weapons and maybe even military personnel to function while undetected. UCSD scientists have tested the “first effective dielectric metasurface material—an ultra-thin, … [Read more...]

GaN Coaxial Power Amplifiers
Pasternack recently launched its increased offering of gallium nirtride (GaN) coaxial power amplifiers. “The high power density of gallium nitride semiconductor technology dissipates heat more effectively which results in amplifier designs that have significantly higher output power levels over broadband and narrowband frequencies,” according to the company. This technology … [Read more...]
New Metamaterial Yields Invisibility for Aircraft and Drones
Electrical engineers from the University of California have created a new ultra-thin metamaterial that could provide a cloaking device and make UAVs (Unmanned Aerial Vehicles) invisible. The new material creates invisibility and leaves no electronic, infrared or visual signatures for enemies to detect. The new design uses “an ultra-thin Teflon substrate, studded with … [Read more...]
High Power Coaxial Limiters Handle up to 200 Watts
Fairview Microwave Inc. announces a new family of broadband, high power coaxial limiters that protect sensitive components and RF receivers that are close to high power signals. Depending on the model, the limiters operate on frequencies ranging from 0.5 GHz to 40 GHz. The limiters also offer seven different design options, a low leakage power of 10 to 15 dBm and limited … [Read more...]
Electromagnetic Catapult Successfully Installed on Aircraft Carrier
The Navy’s new electromagnetic catapult, the Electromagnetic Aircraft Launch System, (EMALS) has successfully been installed on the USS Gerald R. Ford, replacing the steam catapults previously used to launch aircraft. Because EMALS yields less maintenance, more control, more reliability and a lighter weight, the Navy decided it will be used on all future aircraft carriers in … [Read more...]
Series of Reliable RF & Microwave Power Amplifiers Makes Debut
Fairview Microwave introduces a new family of RF and microwave power amplifiers that offer high reliability and broadband frequency ranges from 0.5 MHz to 20 GHz. The amplifier series is best suited for use in demanding environments and applications such as electronic warfare, military communications, radar, telecom, medical, test & measurement, point-to-point radio and … [Read more...]
New Waveguide Detectors Cover Frequency Ranges from 26.5 to 110 GHz
Pasternack introduces new high performance waveguide detectors that cover frequency ranges from 26.5 to 110 GHz. The detectors are zero biased and perform the best in KA, Q, U, V, E and W frequency bands. Because the detectors are zero biased, no external DC bias or mechanical tuning is needed. The detectors also offer a rugged steel construction, high thermal stability, … [Read more...]
Canted Coil Catalog Describes Benefits for EMI/RFI Shielding
Bal Seal Engineering, Inc. released a new 10-page catalog that describes the benefits of canted coil springs for EMI/RFI Shielding. It “provides engineers and designers with detailed information about how canted coil springs can be used to address electromagnetic interference/radio-frequency interference (EMI/RFI) shielding challenges. It describes how the compact, … [Read more...]
Connector Series Includes EMI Shielding
Mouser Electronics introduces the Amphenol Pegasus series of twist and lock ‘scoop-proof’ connectors with EMI shielding. “EMI shielding is provided by an electroless copper and nickel plate, and a copper alloy spring finger gasket. Tests show greater than 50db of attenuation for low-end signals (<100Mhz) and greater than 40db of attenuation for high-end signals (<1Ghz),” … [Read more...]
Defense Contractor to Produce Electromagnetic Aircraft Launch System
General Atomics, a defense contractor in San Diego, Calif., announced it will produce the Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) for the John F. Kennedy aircraft carrier under a contract from the U.S. Navy. The EMALS system uses bursts of electromagnetic energy to launch planes and jets into the air. It takes up less space on ships, … [Read more...]
