Abstract: A system for treatment of biological tissues is provided. The system can deliver electric pulses to a targeted region within a biological tissue. The system includes an antenna assembly and a lens. The antenna assembly is configured to generate and direct electromagnetic radiation. The lens is configured to be positioned between a surface of the biological tissue and the antenna assembly. The lens can have a plurality of lossy portions. The lens can be configured to be adjustable to create a patient-specific desired electric field distribution by selective positioning of the plurality of lossy portions within the lens.
