In this paper, static and dynamic behavior of a varactor of a micro-phase shifter under DC, step DC and AC voltages and effects of the residual stress on the phase diagram have been studied. By presenting a mathematical modeling, Galerkin-based step by step linearization method (SSLM) and Galerkin-based reduced order model have been used to solve the governing static and dynamic equations, resp...

Low-cost antenna systems are important issues of the recent and the future flexible wireless communication systems. The most flexible satellite to ground/airplane communication systems are based on the phased-array antenna technology. However, the cost of phased array antenna is related to the number of active elements, and the present systems are too expensive for many commercial/military appl...

Abstract In this paper, we introduce simple design equations for optical phase shifter configurations on both single mode and multimode platforms. The are based approximate analytical expressions describing the shift (difference) between two waveguides, one is considered as reference guide second shifter. Different layout geometrical have been studied: step width linear tapering waveguide. vali...

Herein, the mid-infrared (7.7–13.7 ?m) diamond-based phase shifter was designed and optimized by finite-element analysis. The ridge-shaped diamond waveguide is doped to form internal p–n structure, carrier distribution changed applying forward reverse voltages change effective refractive index achieve effect of ?-phase shift. results show that when p-doping concentration 4 × 1017 cm?3 n doping ...

This article presents a novel method for the forward modeling and inverse design of class Schiffman phase shifters using deep neural networks (DNNs). Since DNNs are capable mapping highly nonlinear correlations between inputs outputs, we constructed fully connected DNN to predict electromagnetic (EM) responses given their physical dimensions. Based on this fast accurate tool, cascaded was then ...
