Coupling Matrix Optimizer is a simple, but powerful, GUI that allows microwave filter designers to optimize coupling matrices (which represent coupled-resonator filters). It is especially indicated to obtain coupling schemes for which no formal synthesis procedure exist, as well as extract an equivalent network representation from the EM simulation of a filtering structure.
Define the number of nodes in the CM, filter center frequency and bandwidth. Then, choose the cells of the matrix that you want to optimize by simply clicking on them. Set the goals for your filter and any equality that you wish to enforce. Finally, let Matlab's optimization toolbox adjust the coupling matrix until it provides the result you desire.
Networks with multiple ports (including multiplexers) and/or non-resonating nodes (NRN) are supported.
Several examples are included as references.
