摘要: Department of Physics and Astronomy, University Texas, San Antonio, TX 78249(Dated: September 9, 2007)The electromagnetic dispersion in periodic layered media can be tailored their resonant prop-erties considerably improved by utilizing anisotropic materials. Periodic structures with aphotonic band edge split into two parts, or so-called edge, exhibit superior prop-ertiesincludingexceptionally high Q-valuesof transmission resonances andnearly perfectimpedancematching at the boundaries, even when number unit cells N is not large. A microwave trans-mission resonance Q∼220 demonstrated a stack form-birefringent layers withN=12 realized waveguide geometry.
