Terahertz (THz) waves lie in the electromagnetic spectrum between microwaves and infrared radiation. They are invisible to the human eye. Since they are low in energy, there is no need for be concerned with their impact on human. Today, they play a role in medical and communications technology, but also …

In 2006 the US Defense Advanced Research Projects Agency (Darpa) asked America’s scientists to submit “innovative proposals to develop technology to create insect-cyborgs.” The Hybrid Insect Micro-Electro-Mechanical Systems (HI-MEMS) program, also known as the cybug program, was a proposal from the Defense Advanced Research Projects Agency (DARPA) to encourage the …

In the past, the frequency spectrum ranging from 0.3 to 3THz (or 300 to 3000GHz) was spoken as infamous “Terahertz Gap” as it lies between traditional microwave and infrared domains but remained “untouchable” via either electronic or photonic means. The conventional “transit-time-limited” electronic devices can hardly operate even at its …

Military spectrum requirements are also increasing exponentially as military operations increasingly rely on access to the wireless spectrum in order to assess the tactical environment and coordinate and execute their critical missions. The demand for more and timely information at every echelon is driving an increase in DoD’s need for …

GaN is a semiconductor material that can amplify high power radio frequency signals efficiently at microwave frequencies to enhance a system’s range. Therefore it has become the technology of choice for high-RF power applications that require the transmission of signals over long distances such as EW, radar, base stations and satellite communications. The advantages of GaN-based devices stems largely from the attractive intrinsic physical properties of the material. The material …

The US Air Force Research Laboratory (AFRL) has awarded a new Distributed Radio Frequency Sensing (DRS) contract to Altamira Technologies for next-generation radio frequency (RF) sensing technologies. Valued at $24.6m, the new cost-plus-fixed-fee contract will continue for a period of five years and will support the development of new …

While the conventional electronics like computers and smartphones is built around silicon integrating billions of transistors and is manufactured using complex, costly and wasteful processes in multi-billion dollar foundries . The printed and flexible electronics aim to replace this by “organic” semiconductors which are long chains of thousands of repeating …

The antenna are required in military for land-based, naval, and airborne communications, as well as communications intelligence (COM- INT) and electronic warfare (EW) systems including communications electronic support measures (CESM) and communications electronic countermeasures (CECM). The aperture size is constrained by the dimensions of the host platform (e.g. aircraft or naval …

Molecular electronics, also called moletronics, is the branch of nanotechnology where the molecular building blocks are used for the fabrication of electronic components. It is an interdisciplinary area that spans physics, chemistry, and materials science. The smaller size of the electronic components decreases power consumption while increasing the sensitivity (and …
