Abstract :
Experimental and theoretical results are presented demonstrating some novel properties of a new class of filters based on inhomogeneous coupled-line structures having large even-odd mode-velocity ratios, e.g., a single inhomogeneous coupled-line filter section with an equiripple, 3-peak stopband and passband response.
