            Abstract : 
Design, simulations, and experiments on a radially inhomogeneous spherical dielectric lens, that is used at the second focal point of a prolate-spheroidal impulse radiating antenna, are presented. This lens is designed to match 100-ps pulses into a biological medium. The higher field amplitude and smaller spot size obtained with such a lens are useful for various bioelectric applications.
