University of Washington (UW) researchers have developed a low-cost, long-range data-communication system that could make it possible for medical sensors or billions of low-cost “internet of things” objects to connect via radio signals at long distances (up to 2.8 kilometers) and with 1000 times lower required power (9.25 microwatts in an experiment) compared to existing […]
FISH-EYE BEAM-SPLITTER Realizing All-Dielectric Devices from Transformation Electromagnetics A team from Oxford and the University of London fabricated and tested a 2-D generalized Maxwell fish-eye lens has been from all-dielectric polymer/ceramic composite materials. The graded refractive index profile of the lens, discretized into a concentric-ring structure, functioned as a two-way beam splitter. Epoxy composites, with […]
Low modulus, compliant systems of sensors, circuits and radios designed to intimately interface with the soft tissues of the human body are of growing interest, due to their emerging applications in continuous, clinical-quality health monitors and advanced, bioelectronic therapeutics. Although recent research establishes various materials and mechanics concepts for such technologies, all existing approaches involve […]
WPT Ultra-Light Rectenna for Harvesting Next-Generation LTE RF Energy A novel, compact, ultralightweight multiband RF energy harvester fabricated of nested annular slots on a paper substrate to operate in all recently released LTE bands (range 0.79-0.96 GHz; 1.71-2.17 GHz; and 2.5-2.69 GHz). The design features an RF-to-dc conversion efficiency in the range of 5%-16% for […]
Silicon has been the mainstay of chips because silicon possesses a “Goldilocks” band gap of 1.1 electron Volts (eV), which makes it possible to operate integrated circuits at a low voltage, leading to reduced leakage of current. Another key feature of silicon is that it can be used to make a convenient “native” insulator, in […]
The first ever I EEE RF & μW Boot Camp was organized by Universidad Autónoma de Guadalajara (UAG), Mexico on July 24th, 2017. After the advent of Latin America Microwave Conference (LAMC 2016), there was a greater need of involving Young Professionals to provide them better insight in RF & Microwave practical design work. With […]
NONLINEAR OPTICS Terahertz Quantum Cascade Laser Frequency Combs Quantum cascade lasers have shown tremendous potential for generating frequency combs in the mid-infrared and terahertz regions. Four wave mixing (FWM) is the main comb formation process. Group velocity dispersion (GVD) is the main comb-degradation mechanism. And spatial hole burning (SHB) has a considerable impact on whether […]

As we start looking towards more comprehensive exploration of the Moon and of Mars, the assumption is that we’re working on sending humans to the surface of those worlds. It’s going to be exponentially more difficult and dangerous than sending robots, but that’s what exploration is all about, right? There’s an article in the current […]
ANTENNAS Understanding Phase Noise from Vibrating Antennas Vibrating antennas distort signals. Previous analyses have focused on how physical distortion of the antenna structure changes beam patterns. The vibrational velocity and acceleration also have an effect, however, producing Doppler distortions that contribute heavily to noise at vibration frequencies up to 1000 Hz. CALL FOR PAPERS Substrate […]
MTT25 and MTT10 are jointly sponsoring a half-day workshop on Microwave Nano-biotechnology on June 9, 2017 as part of IMS 2017. The field of nano-biotechnology sits at the intersection of two rapidly growing fields of research. The ongoing push to scale electronic devices to nanometer-scale and even atomic dimensions has led to the discovery of […]
Matteo Stocchi (PhD student at the University Politecnica delle Marche) and Michael Haider (PhD student at the Technical University of Munich) gave presentations at the Student Design Competitions of the 2017 IEEE Microwave Theory and Techniques Society (MTT-S) International Microwave Symposium (IMS) on Tuesday, Jun 6th, 2017 in Honolulu, Hawaii. The competition was entitled “Apps […]

Take your time to browse through the IMS/RFIC workshop program and join us for these events to hear about the latest developments and discussion with experts in these field.The student design competition is:- 5G Mobile […]
– Monday: high power WPT, organizers: Alessandra Costanzo and Zoya Popovic- Friday: Low-cost technology for Space applications: organizers: Nuno Carvalho, Alessandra Costanzo
As part of the International Microwave Symposium 2017 (June 4-9, 2017) the RF nanotechnology technical committee is sponsoring a student design competition entitled “Apps for Radio-Frequency Nanotechnology.” The main motivation for application of nanotechology to electronics is to define new functionalities and new concept devices, beyond Moore, exploiting the unique features of nanostructured materials. For […]
