In this research, we study the radiative eigenmodes in two dimensional metallic slit arrays by using THz time-domain spectroscopy (THz TDS). Understanding these modes will help us in further study on the resonant interaction between them and the electron beam, and subsequently to improve the extraction of terahertz radiation.
