Abstract
A transmission line ( ) is formed to have a characteristic impedance which increases at a first substantially exponential rate with respect to a distance from the input ( ). A plurality of resonators ( ) are coupled to the transmission line and positioned at a plurality of locations along the transmission line. The plurality of resonators has resonant frequencies that decrease at a second substantially exponential rate with respect to the distance from the input. An output signal ( ) is obtained at a point in the filter that produces a filter response having a corner frequency.
