Abstract

A polarization selective screen allowing only electromagnetic waves having a desired linear polarization to pass therethrough, the screen includes an array of relatively thin, parallel and evenly spaced conductive flat ribbons supported between end portions of a frame structure, the broad surface of the ribbons being orthogonal to the plane of the screen and being supported and maintained in place under a predetermined tensional force by tension means such as spring-loaded ribbon hangers.
