Superconducting reflection filter

摘要: An optical reflection band filter structure for selectively blocking radiation within a preselected range of wavelengths is described which comprises plurality multipole elements configuration deposited with prescribed spacing in periodic array on substrate dielectric material, each comprising central element metal and having shape corresponding to the overall spaced segments, space between adjacent segments being filled segment material characterized by transition from superconducting phase insulating upon heated characteristic temperature, disposed outwardly center lesser thickness than, or different composition from, next inwardly segment, innermost substantially equal that element.
