Abstract
A twistarray reflector includes: a reflector having front reflecting surface comprising wires and a back reflecting surface, the front reflecting surface fabricated from the wires and composites where the wires are placed having an orientation at each point on the front surface to decompose an incident field into orthogonal components so that an electromagnetic reflected from the front surface when superposed with a phase-inverted electromagnetic field reflected from the back reflecting surface produces a net reflected electromagnetic field that is polarized in a specific vector direction with consistent phase.

A twistarray reflector comprising:
- a first reflective surface comprising a trace path of distorted-spiral wires disposed about a center ring and extending to a periphery of the first reflective surface;
- and
- a back reflecting surface disposed a distance from the first reflective surface, wherein each one of the distorted-spiral wires has a trace tip where the trace tips approaching an axisymmetric center are shorted together in the center ring to preclude E-field-induced breakdown from charge accumulating at ends of the traces.
A twistarray reflector comprising:
- a first reflective surface comprising a trace path of distorted-spiral wires disposed about a center ring and extending to a periphery of the first reflective surface;
- and
- a back reflecting surface disposed a distance from the first reflective surface, wherein each one of the distorted-spiral wires has a trace tip where the trace tips at an outer edge are terminated with a region of enhanced radius to mitigate field-induced breakdown from charge accumulating at the tips.
