Neural networks recently gained attention as fast and flexible vehicles to microwave modeling, simulation, and optimization. After learning and abstracting from microwave data, through a process called training, neural network models are used during microwave design to provide instant answers to the task learned. Appropriate neural network structure and suitable training algorithm are two of th...

Microelectromechanical systems (MEMS) devices have been increasing in popularity for radio frequency (RF) and microwave communication systems due to the ability of MEMS devices to improve the performance of these circuits and systems. This interdisciplinary field combines the aspects of lithographic fabrication, mechanics, materials science, and RF/microwave circuit technology to produce moving...

The design and application of a high-speed digital cross correlator IC, a critical enabling technology for future ocean surface wind instruments based on passive microwave polarimetry, is discussed in this paper. Global ocean wind vector measurements are key to understanding climate variability and prediction, particularly ocean circulation and its response to changes in surface forcing. Recent...

Microwave technology plays a more important role in modern industrial sensing applications. Pushed by the significant progress in monolithic microwave integrated circuit technology over the past decades, complex sensing systems operating in the microwave and even millimeter-wave range are available for reasonable costs combined with exquisite performance. In the context of industrial sensing, t...

Background: Microwave technology has revolutionized histological processing by reducing processing time and improving tissue integrity. We describe the first microwave-accelerated tissue processing procedure for healthy and diseased tissue fragments of two species of corals: the gorgonian Gorgonia ventalina and the scleractinian Acropora cervicornis. Methods: Fourteen tissue samples from sea fa...

The IEICE (Institute of Electronics, Information and Communication Engineers) Transactions on Electronics announces a forthcoming special section on "Microwave and Millimeter-Wave Technology" to be published in October 2016. With the recent and rapid growth of wireless applications (5G, WLAN, WPT system, millimeter-wave radar, sensor), there are increasing demands of high performance/small size...

A new advanced microwave drying technology has been developed using a continuous dryer combined with an air cooler. Principle of the new technology consist in using microwave absorption filters made from special porous ceramics which act as both absorbent and transparent material for microwaves. Ceramic slabs reduce intensity of microwave radiation to such a extent which prevents overheating or...

The U.S. Army’s Future Combat Systems are designed to support the future force with three integrated transformation phases: Concept and Technology Development, Systems Design, Demonstration and Production. The Concept and Technology Developments phase is creating new challenges and opportunities for radio frequency and microwave applications in global positioning, navigation, timing, communicat...

We outline a number of high temperature superconducting Josephson junction-based devices including superconducting quantum interference devices (SQUIDs) developed for a wide range of applications including geophysical exploration, magnetic anomaly detection, terahertz (THz) imaging and microwave communications. All these devices are based on our patented technology for fabricating YBCO step-edg...

The purpose of optical antennas is to convert the energy of free propagating radiation to localized energy, and vice versa. Although this is similar to what radio wave and microwave antennas do, optical antennas exploit the unique properties of metal nanostructures, which behave as strongly coupled plasmas at optical frequencies. It is hoped that optical antennas can increase the efficiency of ...
