Abstract
A method for making a dielectric-slot polarizer includes affixing plural dielectric sheets in a stack with those sheets having the greatest dielectric constant toward the center of the stack. The dielectric sheets may be fused or joined to each other by heat, pressure, or both. A dielectric support sheet is affixed by adhesive to a first side of the stack to form a partially supported stack. Slots are defined through the partially supported stack down to the adhesive. A second dielectric support sheet is adhesively affixed over the slots of the stack to define the polarizer.
