ABSTRACT:
An optical reflection band filter structure for selectively blocking radiation within a preselected range of wavelengths is described which comprises a plurality of multipole elements of preselected configuration deposited with prescribed spacing in a periodic array on a substrate of dielectric material, each multipole configuration comprising a central element having shape corresponding to the overall shape of the multipole and a plurality of adjacent connected segments, all comprising a material characterized by transition from superconducting phase to insulating phase, upon being heated to a characteristic transition temperature, the central element having predetermined thickness and each transition segment disposed outwardly from the center element having higher transition temperature than the next inwardly disposed transition segment, and the central element.
