Abstract
Summary form only given. In this work, a 2 × 2 photoconductive antenna (PCA) array is used in a THz near field imaging setup as THz emitters while the sample is placed close to the antenna array (the antenna-sample distance is about 10 μm). A microlens array is used to couple and focus femto-second laser pulse onto each antenna. The response of a sample of gold pattern on quartz is measured. A FDTD model combined with HFSS simulation is used to predict the time domain current and near field scanning result. Good agreement between simulation and experiment is obtained.
