Increasing trends in the usage of wireless and Electromagnetic (EM) technology in daily life led to concerns for their effects...
Computational electromagnetics (CEM) techniques have become increasingly important with the rapid advancements in technology in areas such as electromagnetic compatibility, antenna analysis, radar signature prediction, cellular phone-human body interaction, design of electrical and medical devices, target recognition and lightning strike simulation. Electromagnetic phenomena are governed by the Maxwell equations, which can be expressed in either the frequency or the time domain.
Our work is focused on the numerical approximation of Maxwell’s equations using finite-element technology. The computational solution of problems
Integration Technology and MMICs
Systems with high demands in operating frequency, output power, low noise, and linearity have important applications in automotive radar, broadband communications, radio relay systems, optoelectronics, cellular phone power amplifications, and the measurements and instrumentations industry. These systems need powerful, monolithic microwave integrated circuits(MMIC).
To meet their performance requirements, designers must use GaAs, InP, GaN, SiGe and other heterostructure compound-semiconductor components. The business environment can pose even greater challenges, such as time-to-market, cost, and reliable design approaches. Modern circuit design must find new ways ...
Wireless Power Transfer
Wireless power transfer works by having a transmitter coil generate a magnetic field; a receiver coil then draws energy from that magnetic field. One of the major roadblocks for development of marketable wireless power transfer technologies is achieving high efficiency. Enhancing wireless power efficiency has been a major goal of OPZET research group. This could help advance efforts to develop wireless power transfer technologies for use with electric vehicles, in buildings, or in any other application where enhanced efficiency or greater distances are important considerations. An efficient wireless power transfer technology may bring about commercial systems that will indeed allow owners to charge electronic devices without any physical contact with the charger. The efficiency achieved by our researchers and the possibility of random orientation make the new system a good candidate for such future commercial applications.
3D Printed Antenna Technology
3D printing technology, and particularly 3D printing the antenna in a single, all-in-one piece, allowed the engineers to ensure an extremely high level of accuracy. Making a simulation based on a complete 3D model of the antenna leads to a significant increase in its accuracy. By using this same model to 3D print it in a single piece, any source of assembly misalignments and errors are removed, enabling excellent results. When it comes to space launches and space technology, weight reduction is a critical strategy that can make or break a successful launch. The use of 3D printing open up possibilities for RF structures that were previously impossible to manufacture with conventional techniques. Designed for future mega-constellation small satellite platforms, it would need further qualification to make it suitable for real space missions, but at this stage, we’re most interested in the consequences on RF performance of the low-cost 3D printing process.
