Abstract :
This paper proposes two new methods to obtain "multizero" stopband filters, using microstrip lines on nanoporous membranes filled with magnetic materials. The first method consists of electrodeposition of multilayered nanowires in the pores of the membrane. In the second one uniform nanowires are rearranged under the strip to form Photonic Bandgaps (PBG) structures. Next, we show that the ferrimagnetic properties of the nanowired substrate can be used to fabricate a planar circulator topology yielding nonreciprocal effects without applying a DC magnetic field
