Claim Text:
1. A system for treatment of biological tissues, comprising: a lens having a hollow, substantially hemispherical shape with an outer surface, an inner surface, one or more lossy portions, and a dielectric constant increasing monotonically from the outer surface to the inner surface, the inner surface defining a substantially hemispherical cavity for inserting the biological tissues; and an antenna assembly for generating electromagnetic energy via a series of pulses having a transient time of less than about 1 nanosecond and directing the electromagnetic radiation towards the outer surface; wherein the lens is configured to direct the electromagnetic radiation to an area in the cavity, wherein the dielectric constant of the lens at the inner surface substantially matches a dielectric constant of the biological tissues, and wherein the lossy portions of the lens are configured to attenuate a portion of the electromagnetic radiation being directed to the cavity from at least one direction.
