Abstract: Three-dimensional photonic crystals with a diamond structure composed of YSZ (3 mol% Y<subscript>2</subscript>O<subscript>3</subscript>-stabilized ZrO<subscript>2</subscript>) spheres in a resin matrix were fabricated by using stereolithography. The lattice constant was 12 mm and the diameter of the spheres was 5 mm. These photonic crystals made of ceramic spheres showed complete photonic band gaps at around 12 GHz between the eighth and ninth bands. The propagation characteristics of microwaves agreed well with the calculated results using the plane wave expansion method. [ABSTRACT FROM AUTHOR]
