Abstract
The focusing property of extended hemispherical lens, on which a linearly polarized plane wave is incident normally, is simulated by FDTD method. The focusing process is presented pictorially at different moment. Focal length is obtained and compared with that computed by other method. Good agreement has been found. The coupling between the focused incident wave and a waveguide in the focal plane of the lens is also simulated. The lens is used as antenna at millimeter wavelengths.
