Abstract :
This work proposes a new design procedure of microwave filters using the theory of small reflections. The procedure is a simplification of the inverse scattering problem. The technique consists of determining the obstacle that generates the scattered field. In the case of microwave filters, the field is the time-domain input reflection coefficient and the geometry is the impedance profile of the filter. The procedure can be used to design different kinds of filters
