摘要：

This paper presents an overview of the usage of metamaterial slabs and lens in applicators for hyperthermia cancer treatment procedure. The evolution of metamaterials starts from 2007 until 2017 was traced. The review indicates that Left handed metamaterial (LHM) lens when integrated with an antenna can improve focusing capabilities of the antenna used as an applicator to treat the cancerous area. However, current applicators have poor focal spot when directed towards the actual tumour area. Subsequently, a proposed modified applicator that integrates Left-Handed Metamaterial (LHM) lens with existing antenna is discussed. The proposed antenna termed LHMA is expected to have an improved focusing capabilities which could be used to kill cancerous tissues without severely affecting surrounding healthy tissues. The goal of the research is to reduce unwanted hot-spots developed using current available applicators. The focusing abilites of the proposed appicator will be evaluated using the Specific Absorption Rate (SAR).
