    Coupling Matrix Applied to Dielectric Resonator Filter Design

    I have MATLAB code to generate coupling Matrix for required filtering specifications. I need to realize the filter using Dielectric Resonators. Can anybody provide me with some design guide that describes the procedure to translate coupling matrix into physical filter parameters e.g, Dielectric resonators Diameter, height, Er ?? and the relative position and structure of resonators to meet specific couplings among them as per coupling matrix ?? Kindly help me out .

    Re: Coupling Matrix Applied to Dielectric Resonator Filter Design

    The attached paper describes how to translate the 'g' parameters of the Low Pass Prototype Filter into the Coupling Matrix parameters. You can use the 'g' parameters to determine the sectional series inductance and shunt capacitance. The explanation starts on p. 10.

    I have a Coupling Matrix and am trying to use a gradient-based optimization function to reduce the Cost Function for my Filter. Do you have Matlab code that shows how to apply an optimization method like Matlab's 'solvopt' function to a Cost Function Matrix? I could really use it.
