摘要

The purpose of this research is to investigate the impedance, reflection, and transmission properties of staggered tuned biplanar arrays using the periodic surface theory introduced by Munk. A staggered tuned biplanar array consists of two arrays which resonate at different frequencies. The biplanar arrays are analyzed when placed in an infinite medium or in a stratified dielectric medium. The investigation is in three parts.;In the second part, staggered tuned biplanar arrays of dipoles, which either have widely separated resonant frequencies or slightly different resonant frequencies, analyzed in an infinite medium. Conditions for perfect reflection and transmission are found using a transmission line analogy. For staggered tuned biplanar arrays with slightly different resonant frequencies only one resonant region may result. A two band reflecting FSS was designed with a passband.;In the third section, staggered tuned biplanar arrays of dipoles are analyzed when embedded in one or three dielectric slabs. Again conditions for perfect reflection and transmission are found using a transmission line analogy. Methods for achieving stable resonances with angle of incidence are found. As in the second part staggered tuned biplanar arrays with slightly different resonant frequencies may have only one resonant region. A two band reflective FSS was designed with a passband that achieves stable resonances with angle of incidence.;In the first part, the general theory of periodic surfaces introduced by Munk is summarized. Expressions for the induced voltage, mutual impedance, self-impedance, and scattered fields are presented for a periodic surface. A transmission line analogy is introduced which can simplify the analysis of periodic surfaces.
