ABSTRACT:
Radiofrequency attenuator and method. The attenuator includes a pair of transparent windows. A chamber between the windows is filled with molten salt. Preferred molten salts include quarternary ammonium cations and fluorine-containing anions such as tetrafluoroborate (BF4−), hexafluorophosphate (PF6−), hexafluoroarsenate (AsF6−), trifluoromethylsulfonate (CF3SO3−), bis(trifluoromethylsulfonyl)imide ((CF3SO2)2N−), bis(perfluoroethylsulfonyl)imide ((CF3CF2SO2)2N−) and tris(trifluoromethylsulfonyl)methide ((CF3SO2)3C−). Radicals or radical cations may be added to or electrochemically generated in the molten salt to enhance the RF attenuation.
