In all hyperthermia schemes with left-handed metamaterial (LHM) lens applicator, water bolus are used to prevent skin from being overheated during the hyperthermia treatment. Owing to water's high refraction index, high reflection usually occurs at the interface between low-index LHM lens and water bolus, and between water and skin, which will lead to the low efficiency of hyperthermia. In this paper, we propose a new LHM lens applicator with built-in cooling feature for superficial tumor hyperthermia. Both simulation and experiment demonstrated that microwave hyperthermia with the proposed applicator may concentrate more microwave energy into deeper tissue if compared to hyperthermia with normal LHM lens.
