In this paper, the authors extended free space radiation mode (FSRM) method to the analysis of dielectric waveguide discontinuities and propagation in fully three dimensional structures.Abstract:
The well established free space radiation mode (FSRM) method is extended to the analysis of dielectric waveguide discontinuities and propagation in fully three dimensional structures. Unlike beam propagation methods (BPM) the method intrinsically incorporates continuous reflections and is inherently wide angled in nature. Results are given for a representative selection of practical structures, such as single and double step discontinuities and tapers, for both TE and TM polarisations. The method is computationally efficient with minimal memory requirements.read more
