Analysis of coupling characteristics of rectangular core optical waveguide coupler
A theoretical formulism based on the boundary matching technique has been proposed to study the systematic of an asymmetric waveguide coupler. Same formulism is applicable to a symmetric coupler. The equivalent parallel coupling length to account for the coupling in the two S-shaped regions in the input and the output of the coupler is obtained from the coupler geometry and is dealt with more a...
متن کاملElectromagnetic Field Coupling to Transmission Lines Inside Rectangular Resonators
In this paper the current inside a cavity, which is induced by lumped and distributed sources, is calculated. The current is obtained analytically (Green’s function method) and numerically (MoM – and MLFMM – method). A long, parallel wire is chosen that connects two opposite walls of a rectangular resonator. Since the conductor conserves the translational symmetry of the resonator in one direct...
متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولRadiation and Absorption Losses of the Whispering-Gallery-Mode Dielectric Resonators Excited by a Dielectric Waveguide
The scattering of a surface wave of a dielectric layer backed by a ground plane from the whispering-gallerymode dielectric resonators is considered by use of the surface potential approach and analytical regularization. Efficient numerical algorithms have been developed with applications to the bandstop filter design. Transmitted and reflected power fractions and radiation and absorption losses...
متن کاملAccurate Analysis of Dielectric Backed Planar Conducting Layers of Arbitrarily Shaped in a Rectangular Waveguide
The characteristics of dielectric backed planar conducting layers of arbitrarily shaped in a rectangular waveguide are calculated by means of coupled integral equation technique (CIET) which accurately takes higher order mode interactions. Equivalent structures for the accurate analysis whole structure are introduced in which magnetic surface currents are identified as the unknowns at the apert...
