Characterization of subwavelength-scale marginal roughness from far-field irradiance

Jyh Long Chern, Shu Chun Chu

Research output: Chapter in Book/Report/Conference proceedingConference contribution


A constructed-aperture approach is proposed to measure marginal roughness by far-field irradiance. It is numerically shown that spatial profile could be retrieved with an error less than 3%, even its variation is in subwavelength scale.
