A near-field antenna structure is described that is an effective delivery tool for radiofrequency (RF) and microwave power to achieve coagulative necrosis in metastatic tumors while reducing or eliminating thermal conduction along the structure. This tool is a probe small enough to be used safely virtually anywhere in the neck, chest, abdomen, and pelvis, and be guided by computerized tomography (CT) or ultrasonic imaging.
