Abstract

Different metamaterials and electromagnetic metal/dielectric structures are simulated with the aim to improve the characteristic of a low-cost mini-invasive needle applicator designed for hyperthermia therapy of cancer. Preliminary investigations, following different approaches, have been focused to increase the device feasibility and patient wellness. In particular, the starting applicator is a needle hosting a coaxial antenna operating at frequency 𝒇=𝟐.𝟒𝟓 𝑮𝑯𝒛 in the Industrial, Scientific, and Medical (ISM) frequency band. The constructed and characterized 16G prototype, allowing promising performance, could be further enhanced by considering suitable metamaterial layers covering the radiating slot made of Teflon.
