Inhomogeneous coupled line devices
Abstract
A new type of electrical filter has been developed which has a very simple physical structure but is capable of producing a complicated multipole/multizero response even from a single section. The filters are based on inequality of propagation mode velocities of coupled lines in inhomogeneous media. Design procedures, theoretical and experimental results are given for single and multi-section filters.
