The literature describing scattering matrices for semi-analytical methods almost exclusively
contains inefficient formulations and formulations that deviate from long-standing convention …

The total-field/scattered-field (TF/SF) formulation is a popular technique for incorporating
sources into electromagnetic models like the finite-difference frequency-domain (FDFD) …

The propagation characteristics of surface waves with periodic waveguides is examined
based on the characterization of a unit cell through the generalized conservation of complex …

There is tremendous demand for numerical methods to perform rigorous analysis of devices
that are both large scale and complex throughout their volume. This can arise when devices …

This paper discusses the physical nature and the numerical modeling of a novel approach of
periodic structures for applications as photonic sensors. The sensing is based on the high …

A compact 90° three-branch beam splitter is proposed. The device relies on the use of a
high contrast material system. It utilizes a rectangular resonant cavity for its operation, which …

This paper considers abnormal blocking of a guided mode propagating in a silicon optical
waveguide with periodic tunnelling inserts. Using an independent two-dimensional analysis …

Abstract The Method of Lines is a semi-analytical versatile tool for the solution of partial
differential equations. For the analysis of spatial complex linear waveguide structures, this …

A long range surface plasmon polaritons Bragg grating is investigated by a complex mode
