Abstract
A light weight parallel plate polarizer (100) employs a sandwich construction design including a polarizer section (102) and a foundation section (104). The polarizer section (102) is formed from low dielectric constant, low density foam or honeycomb layers (112) alternating with polarizer panels (110). The foundation section (104), which supports the polarizer section (102), is formed from a low density, low dielectric constant foundation material. In an alternate embodiment of the present invention, the light weight parallel plate polarizer employs a suspension design (400). The suspension design (400) includes individual sections of dielectric mesh (602) which support polarizer plates (402). The individual mesh sections (602) are suspended between first and second support posts (404, 406) and compression springs (410) may be provided for adjusting and maintaining the tension in the mesh sections (602).
