Abstract

A study of metal hole array (MHA), a metal plate with a periodic subwavelength hole array, has been attracted a significant research interest due to its extraordinary phenomena within the surface resonance states’ (SRSs) bandgap when electromagnetic waves passing through it [1]. A thin MHA, which exhibits a beam-collimating effect, is a promising novel device which can be used in ultra-fast terahertz (THz, 0.1–10 THz) wireless communication in the future. Recently, we have proposed an electro-optic (EO) sensing system, which is based on non-polarimetric self-heterodyne EO detection technique, in order to visualize the THz waves in the near-field region to characterize THz devices [2]. Our system is able to measure the amplitude and phase of THz waves simultaneously with the high accuracy, high repeatability and broad frequency tunability. In this study, we visualize and characterize the beam-collimating effect of the MHA at 125 GHz.
