Microwave ablation - Wikipedia The technique for thermal ablation in the lung by using radiofrequency ablation was first described in 1995 for use in animal lung tumor models and then in 2000 in humans. [1-2] Microwave ablation has emerged as a newer ablation modality and an addition to the arsenal of minimally invasive cancer care. Advances in Mechanical Engineering 2018, Vol. 10(8) 1–13 A ... the antenna is enclosed in a catheter which made of polytetrafluoroethylene (PTFE). Figure 1 displays the geometry of a single-slot MW antenna. The working frequency of the antenna is 2.45 GHz, a widely used frequency in MW ablation. The dimensions of the single-slot MW antenna are shown in Table 1, while its dielectric properties are listed in ... Design And Analysis Of Two Slot Antenna For Microwave ...
