Abstract
A dielectric-slot polarizer arrangement includes a first dielectric polarizer plate with first elongated aperture arrangement, and second and third dielectric polarizer plates, also defining elongated aperture arrangements parallel to or registered with the first aperture arrangement. The second and third dielectric plates sandwich the first plate. The bulk dielectric constant of the first plate exceeds that of the second and third plates. The effective perpendicular and parallel dielectric constants of the first plate exceed those of the second and third plates. Ideally, the dielectric plates are free of metal.
