Abstract
This paper presents an overview of metamaterial slabs or lens as an integrated structure for applicators used in hyperthermia cancer treatment procedure. Hyperthermia treatment procedure (HTP) is a new technique that exposes a cancerous tissue by increasing tissue temperature until 41 °C to 45 °C at a certain period with electromagnetic radiation. Based on the previous study, by moving the microwave sources relative to the metamaterial (MTM) lenses from a tumor/cancer phantom alters the concentration of heating within biological tissue. In this paper, the overview of a metamaterial study on HTP from 2009 to 2019 was carried out. This study indicated that the left-handed metamaterial (LHM) lens was observed to be able to improve the focusing capabilities of HTP on the treated tissue. However, a further study is significantly required to provide different focus position distances on the treated tissue for different stages of cancer. Therefore, a modified HTP applicator integration with an MTM lens structure was proposed. It is aimed to improve focus position distance on the treated tissue and to reduce unwanted hot-spots on surrounding healthy tissues simultaneously. The proposed modified structure was presented in this paper. Specific absorption rate (SAR) simulation was carried out with SEMCAD X 14.8.4 to obtain a SAR distribution for determining penetration depth and focusing position distance on the treated tissue
