The introduction of defects in a photonic band-gap (PBG) material breaks its periodicity, and produces interface states of the electromagnetic field, at frequencies within the stop-bands, manifested by sharp peaks in the transmission response of the structure. We study PBGs properties in the presence of multiple periodicity interruptions, by using a full-wave approach. Results are presented, both for TE and TM polarizations, showing the transmission efficiencies as a function of the involved parameters. We discuss how the selectivity and the position of the transmission peaks inside the stop-band can be controlled. We show that a pass-band filtering behavior can also be obtained.

Abstract
The introduction of defects in a photonic band-gap (PBG) material breaks its periodicity, and produces interface states of the electromagnetic field, at frequencies within the stop-bands, manifested by sharp peaks in the transmission response of the structure. We study PBGs properties in the presence of multiple periodicity interruptions, by using a full-wave approach. Results are presented, both for TE and TM polarizations, showing the transmission efficiencies as a function of the involved parameters. We discuss how the selectivity and the position of the transmission peaks inside the stop-band can be controlled. We show that a pass-band filtering behavior can also be obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
