Abstract :
The gradient based optimization technique along with a new definition of a cost function is applied to the synthesis of coupled resonator filters. The cost function is defined using location of zeros and poles of the filter´s transfer function. The topology of the structure is enforced on each step of optimization and its physical dimensions are uses as independent variables.
