In this paper, a novel modified dielectric frequency selective surface (MDFSS) is proposed and analyzed under 3-D plane wave incidence. Unlike classic DFSS, this MDFSS can easily be developed. The electromagnetic analysis is carried out using the Multimode Equivalent Network (MEN) approach. A new development of electromagnetic fields in non homogeneous dielectric regions is proposed in order to correctly define the Z or S matrix of these blocks. Results are shown for an MDFSS which ensures total reflection with a larger bandwidth than the classic DFSS. Bandwidth can be enlarged and modified by doubling the MDFSS. Similarly, two MDFSS can be combined to ensure total reflection for elliptically polarized wave incidence.

Abstract
In this paper, a novel modified dielectric frequency selective surface (MDFSS) is proposed and analyzed under 3-D plane wave incidence. Unlike classic DFSS, this MDFSS can easily be developed. The electromagnetic analysis is carried out using the Multimode Equivalent Network (MEN) approach. A new development of electromagnetic fields in non homogeneous dielectric regions is proposed in order to correctly define the Z or S matrix of these blocks. Results are shown for an MDFSS which ensures total reflection with a larger bandwidth than the classic DFSS. Bandwidth can be enlarged and modified by doubling the MDFSS. Similarly, two MDFSS can be combined to ensure total reflection for elliptically polarized wave incidence.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
