Abstract

Spectroscopic and imaging analyses using electromagnetic waves in the far IR or submillimeter region [0.1-20 terahertz (THz)] are emerging technologies in the field of optics research. Thanks to recent advances in related science and technology [l]-[6], it has been proposed that THz technology be applied in many fields such as early diagnosis of cancer, detection of counterfeit bills, and moisture analysis.
