✦ Synopsis

A new method for refractive index adaptive meshing based on grid interfacing at material boundaries in "nite-di!erence time-domain (FDTD) methods is presented. It allows highly e$cient simulation of structures consisting of homogeneous regions with large di!erences in refractive index, which are frequently encountered when modelling light-sensitive semiconductor devices on which light impinges from vacuum. In addition to the superior computational performance, this method gives more accurate results for certain test problems than standard FDTD. The stability of the method is demonstrated by means of test example problems.

## Abstract In this paper, we present a hybrid coordinate FDTD scheme, in which we insert a local conformal coordinate system which conforms with the scatterers in a Cartesian coordinate system, when there exists a nonrectangular scatterer in the Cartesian coordinate system. We propose a new interp
