Resonant Inc. announced that Dr. Victor Plessky, the Director of Engineering, will present the Company’s recent breakthroughs in the development of RF filters at the IEEE International Ultrasonics Symposium in Tours, France, from September 18-21, 2016.
At the symposium, Dr. Plessky will present a paper titled, “Hierarchical cascading in 2D FEM simulation of finite SAW devices with periodic block structure”. Electroacoustic simulation using the finite element method (FEM) can be employed to develop surface acoustic wave (SAW) filters and has the key advantage of being highly-flexible; however, FEM simulations typically require significant time and computing power. Dr. Plessky will present a new FEM simulation method that the Company believes is highly-accurate and significantly faster than traditional methods. In the future, they believe it will be possible to apply these same techniques to other acoustic resonator technologies, such as bulk acoustic wave (BAW) and Film Bulk Acoustic Resonator (FBAR).
The presentation is based on a paper written by key researchers at Resonant, including Dr. Panagiotis Maniadis, Dr. Balam Willemsen, Dr. Patrick Turner, Dr. Bob Hammond and Neal Fenzi, as well as Dr. Julius Koskela and Dr. Victor Plessky of GVR Trade SA.
A leading driver of today’s RF filter market are smartphones that can contain in excess of 30 RF filters to support the increasing number of data bands used by carriers. The number of filters is expected to nearly double in the coming years, which will require more board space, increase product costs and draw more power from the battery. More complex filter designs and architectures that help solve these problems will be required to support the new wireless technologies.
Resonant’s simulation breakthrough claims to provide SAW filter developers significant benefits by offering the ability to quickly develop and iterate new products, thereby driving down costs without sacrificing phone design flexibility.
