Beschreibung

This book is intended to give an overview on the latest SAW technologies such as design and simulation of resonator-based devices employing the SH-type leaky SAW. Although vario- us theoretical backgrounds relevant for simulation and de- sign techniques are explained in detail the mathematics of the description was kept as simple as possible.

Klappentext

Surface acoustic wave (SAW) devices are widely used in mobile communications, a rapidly evolving market. This book gives an overview on the latest SAW technologies with an emphasis on the design and simulation of devices, such as resonator-based devices employing the SH-type leaky SAW.
