Abstract
The coupling between copper wire and a THz electromagnetic wave is one of the important factors to build up the magnitude and spectrum of a THz wave. We measured a I THz spectrum range THz pulse into a $480{\mu}m$ diameter and 23cm long copper wire waveguide. We measured THz pulses up to $275{\mu}m$ air gap between the end of the copper wire and transmitter or receiver chips. The coupling sensitivity of the transmitter is 3 times bigger than that of the receiver. The THz pulses propagated to air by the end of the receiver-side copper wire tip acting as a transmitter antenna. We confirmed that the THz field concentrates near the copper wire surface by opening the pin hole to the copper wire waveguide.
