In this paper, the electromagnetic behavior of waves created by a line source through a planar waveguide that is partially filled with a biaxial anisotropic dispersive metamaterial is numerically studied. The finite-difference time-domain (FDTD) method based on the piecewise linear recursive convolutional algorithm (PLRC) in conjuction with the convolutional perfectly matched layered (COML) is employed...
A directivity of radiation from a line source coupled to 2D electromagnetic crystals is investigated using a Fabry-Perot resonator model for the coupled radiating structure. It is shown that the directivity is characterized by the transmission windows of the electromagnetic crystals in the frequency and angular spectral domains and the transverse resonance condition in the space surrounded by the...
A novel formulation of emission from a line source covered by an electromagnetic crystal embedded in a magnetized ferrite slab with a perfectly conductive reflection-plate is described. The method employs the spectral domain approach. The spectral response of electromagnetic crystal embedded in a magnetized ferrite slab is calculated using the lattice sums, the T-matrix of a circular cylinder in magnetized...
