Abstract In this paper, a sub-wavelength metal-insulator-metal (MIM) waveguide structure is proposed by using cross-shape rectangular cavity, of which wings are coupled with two cavities. Firstly, cavity placed between the input and output MIM waveguides. According to mutual interference bright dark modes, three Fano resonant peaks generated. Secondly, adding on left wing cross shaped one, five...

Abstract: A simple and efficient CAD model based on cavity model analysis is proposed to compute accurately the resonant frequency, input impedance, bandwidth and gain of radome loaded rectangular patch antenna. The computed values for wide range of radome parameters are compared with different theoretical and experimental values available in open literature. The computed values employing the p...

The application of edge-elements for modeling three-dimensional inhomogeneously-lled cavities is presented in this paper. Explicit representations for the two element matrices, S] e and T ] e , are provided in order to facilitate the implementation of the FEM formulation. Also included are the results of a numerical experiment that investigates the rate of convergence of the computation of the ...

Numerical simulation of the bifurcation of Bingham fluid streamline topologies in rectangular double-lid-driven cavity, with varying aspect (height to width) ratio A, is presented. The lids on the top and bottom move at the same speed but in opposite directions so that symmetric flow patterns are generated. Similar to the Newtonian case, bifurcations occur as the aspect ratio decreases. Special...

Bose-Einstein condensation of a relativistic ideal Bose gas in a rectangular cavity is studied. Finite size corrections to the critical temperature are obtained by the heat kernel method. Using zetafunction regularization of one-loop effective potential, lower dimensional critical temperatures are calculated. In the presence of strong anisotropy, the condensation is shown to occur in multisteps...

Numerical simulations were used to design a variety of high-Q resonant cavities for integration into a terahertz 2D photonic crystal waveguide. After fabrication, the transmission characteristics of each integrated cavity were explored. These photonic waveguide-coupled cavities demonstrate resonances with linewidths approaching 10 GHz. The results compare favorably to previous observations of r...

In this paper, Lattice Boltzmann Method (LBM) is used to study laminar flow with mixed convection heat transfer inside a two-dimensional inclined lid-driven rectangular cavity with aspect ratio AR = 3. Bottom wall of the cavity is maintained at lower temperature than the top lid, and its vertical walls are assumed insulated. Top lid motion results in fluid motion inside the cavity. Inclination ...

Simultaneous Planar Laser Scattering (PLS) imaging and fluctuating pressure measurements have been made for a rectangular cavity in a Mach 5 turbulent boundary layer.
