Abstract:

To explore the applicability of single-negative materials pair(SNGP) in microwave devices,we established an equivalent transmission line model of reflection-typed band-stop filters based on SNGP.Its working principles and the design method were studied,and then the simulation on its performances was carried out.Results show that the filters perform well in a certain frequency range,which verifies that the method is feasible.
