Abstract
The focusing property of extended hemispherical lens, on which a linearly p olarized 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 agreemen t has been found. The coupling between the focused incident wave and a wave guide in the focal plane off the lens is also simulated. The lens is used a s antenna at millimeter wavelengths.
