Accurate simulation of reflector antennas by the complex source-dual series approach
(Institute of Electrical and Electronics Engineers, 1995-08)The radiation from circular cylindrical reflector antennas is treated in an accurate manner for both polarizations. The problem is first formulated in terms of the dual series equations and then is regularized by the ... -
Enhanced transmission of electromagnetic waves through split-ring resonator-shaped apertures
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2011-06-21)The design of aperture shape is a promising approach for enhanced transmission through a subwavelength aperture. We designed split-ring-resonator (SRR)-shaped apertures in order to increase the transmission through ... -
Radar cross-section study of cylindrical cavity-backed apertures with outer or inner material coating: the case of H-polarization
(Institute of Electrical and Electronics Engineers, 1995-05)A dual-series-based solution is obtained for the scattering of an H-polarized plane wave from a slitted infinite circular cylinder coated with absorbing material from inside or outside. For both cases, numerical results ... -
Simultaneously opening transmission channels with negative and positive phase velocities for the stacked subwavelength apertures in fishnet metamaterials with hybrid unit lattices
(S P I E - International Society for Optical Engineering, 2012-10-05)Hybridization of the unit lattice along the propagation direction was demonstrated to produce a negative-phase-velocity transmission band in the absence of the contributions from the higher diffraction orders for a stacked ...
