New Paper in PRL

Physical Review Letters have published our paper “Optimal radiation of body-implanted capsules.” We investigate the radiation of body-implanted capsules and obtain the explicit radiation optima for arbitrary sources. Established fundamental bounds exceed by far the efficiencies obtained by conventional designs. Based on the results, we synthesize the optimal source that outperforms the existing systems by a factor of five. It allows for safer, more power-efficient, and higher throughput devices.
