Abstract

A simple alternative way to position dielectric materials in the finiteโ€difference timeโ€domain (FDTD) Yee cell grid is proposed. Planeโ€wave illuminated spheres are used as examples to study the performance of the alternative method compared to the standard FDTD method. Although the performances are generally equally good, the alternative method may sometimes give significantly improved accuracy. ยฉ 2008 Wiley Periodicals, Inc.

## Abstract This article presents an efficient tensor based finiteโ€difference timeโ€domain (FDTD) scheme for modeling sloped interfaces in lossy media. The formulated scheme achieves its improved efficiency by implicitly solving the internal fields affected by an interface. This permits the reductio

## Abstract The heart of a chemical sensor based on bulk or surface acoustic wave devices is a polymerโ€coated piezoelectric substrate that selectively sorbs and concentrates the target analyte vapors. The development of such sensors often necessitates the screening and evaluation of suitable polyme
