Researchers Develop ‘Snake-Like’ Flexible Metamaterial Absorber
Korean researchers have developed a flexible “snake-shaped” metamaterial absorber with the ability to suppress electromagnetic radiation. Scientists have studied metamaterials since the late 19th century, when artificial dielectrics were developed just after World War II. These artificial materials are specially engineered to affect electromagnetic radiation, sound or seismic … [Read more...]
New Single-Photon Optical Transistor Could Lead to Faster Data Transmission
Using an ultracold quantum gas, researchers at the Max Planck Institute of Quantum Optics in Germany have created a new kind of transistor-like optical amplifier that allows for a twentyfold amplification of single-photon signals. Although fiberoptic technology has helped speed along data transmission and telecommunications in general, researchers have hoped to find another … [Read more...]
TVS Arrays Provide Board-Level Circuit Protection in Wireless and Telecom Equipment
ProTek Devices has introduced a new family of multi-line low-capacitance (5pF) transient voltage suppressor (TVS) arrays that provide board-level circuit protection in wireless and telecommunications equipment. The SMP6LLC05-2P - SMP6LLC12-2P series consists of three TVS array components with varying minimum breakdown voltages. The SMP6LLC05-2P has a minimum breakdown voltage … [Read more...]
Low Noise Amplifier Offers Wideband Performance for Telecom, Military and Test Instrumentation
Custom MMIC, developer of performance-driven monolithic microwave integrated circuits (MMICs), has released the CMD206, a new DC-50 GHz distributed low noise amplifier in die form. Suitable for microwave radio and VSAT, telecom infrastructure, military and space, test instrumentation and fiber optics applications, the CMD206 features DC to 50 GHz operation with a noise figure … [Read more...]
Optical Cables Made of Air Could Boost Laser Communications
A breakthrough in the development of waveguide technology could extend the reach of light signals to support long-range laser communications and environmental monitoring in the upper atmosphere and beyond, reports new research from scientists at the University of Maryland. Known as an “air waveguide,” the new technology acts much like a fiber-optic cable, guiding light beams … [Read more...]
Beam-Switching Antenna Compensates for Aircraft Movement
A software-defined, electronically-reconfigurable antenna technology developed by researchers at the Georgia Institute of Technology has now been tested on land, in the air and on the ocean. U.S. Department of Defense representatives attended an event earlier this year in which the capabilities of Georgia Tech’s Agile Aperture Antenna (A3), which can change beam directions in … [Read more...]
RF Rotary Joints Prevent Cable Entanglement During Antenna Testing
Microwave and RF product supplier Fairview Microwave has released a new line of single channel/single-axis and single-channel/multi-axis RF rotary joints. Fairview’s RF rotary joints are designed to be used wherever RF signals have to be transmitted between stationary and moving parts of a system, including commercial and military radar, land-mobile radio communications and … [Read more...]
