Abstract
In this report we present our experimental study on a super-focusing effect of a V-groove metallic structure for THz pulsed waves. Without using coupling lens, a 17% amplitude transmission of THz broadband waves (0~2.5 THz) through a 2-μm bottom-width was observed without significant waveform distortion and phase delay.
