Equivalent Circuit Model for Square Ring Slot Frequency Selective Surface
An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...
متن کاملGeneralized Equivalent Circuit Model for Transverse Waveguide Slots and Applications
A generalized equivalent circuit model for waveguide transverse slots is proposed for the efficient analysis of waveguide transitions and waveguide slot antennas and slot-excited antennas. The transverse slots on the broad and end waveguide walls analyzed in this paper are decomposed into three structures: two apertures and an auxiliary waveguide section. The slot aperture in the host waveguide...
متن کاملEquivalent circuit of a reconfigurable triple-slot reflectarray cell
Abstract : This paper presents an equivalent model for a multiple-resonance reflectarray cell. It allows predicting the different phase-states of the cell from only a very few full-wave simulations. Demonstrations are first given for a passive cell where different geometrical parameters are varied. Then, the approach is generalized to a reconfigurable cell. Finally, a canonical reflectarray wit...
متن کاملOne-dimensional photonic crystal slot waveguide for silicon-organic hybrid electro-optic modulators.
In an on-chip silicon-organic hybrid electro-optic (EO) modulator, the mode overlap with EO materials, in-device effective r33, and propagation loss are among the most critical factors that determine the performance of the modulator. Various waveguide structures have been proposed to optimize these factors, yet there is a lack of comprehensive consideration on all of them. In this Le...
متن کاملEquivalent waveguide model for parabolic index planar segmented waveguides
In this paper we outline a simple procedure to obtain an equivalent z-invariant waveguide for a given graded index segmented waveguide. In particular, the proposed model is shown to predict accurately the modal spot size and the effective indices of the fundamental and the first higher order modes of a planar parabolic-index segmented waveguide over the entire range of duty cycles. The result s...
