Microwave absorptions of ultrathin conductive films and designs of frequency-independent ultrathin absorbers
We study the absorption properties of ultrathin conductive films in the microwave regime, and find a moderate absorption effect which gives rise to maximal absorbance 50% if the sheet (square) resistance of the film meets an impedance matching condition. The maximal absorption exhibits a frequency-i...
