✦ Synopsis

The nonreciprocal phenomena of a gyrotropic thin-film waveguide with a grating configuration have been analyzed by the singular perturbation technique with multiple space scales. The analyzed structure can perform both as a grating coupler and an isolator. With low gyrotropy, the beam deflection is not perturbed very much, and the performance depends critically on the thickness of the film layer and the off-diagonal element of the permittivity tensors in the YIG medium.

This paper deals with the numerical modelling of arbitrarily shaped curved antennas by marching on in time (MoT) technique. This time domain version of the method of moments (MoM) is particularly suitable for transient analysis and, in this respect, is more e$cient than the frequency domain approach

## Abstract In this paper, a matched load termination of a finite‐length line is used to represent an infinite feedline structure in FDTD simulations. A generator with an internal resistor—which is matched to the input port—is employed to excite the feedline, with a view to achieving a low reflecti
