摘要：
A system for applying microwave energy to the skin, comprising: a signal generator (304) adapted to generate a microwave signal having an electric field component； an applicator (320) comprising one or more microwave antennas (358) and an interface for tissue contact (362), the applicator (320) connected to the signal generator (304) and adapted to apply the microwave signal to the skin, in which the microwave signal has an electric field component； a vacuum source (308) connected to the tissue chamber； a tissue chamber adapted to move a skin surface (1306) in thermal contact with a cooling plate (340) at the interface for tissue contact, the cooling plate being oriented relative to the antenna to be parallel to the electric field component of the microwave signal； a source of refrigerant (310) connected to said interface for tissue contact (362) and adapted to cool the skin in thermal contact with the interface for tissue contact； and a controller (302) adapted to control the signal generator (304), the vacuum source (308) and the refrigerant source (310), wherein the one or more microwave antennas (358) are configured to radiate the microwave energy inside the skin, with microwave energy having a frequency and orientation of the electric field that generate a standing wave pattern that has a maximum of constructive interference in a target tissue, thereby creating a maximum temperature in the tissue target, creating a lesion core (1321)； wherein the source of coolant removes heat from the skin surface (1306) and at least an upper part of the skin's dermal layer (1305) to prevent heat from diffusing into an upper part of the dermal layer of the skin (1305)； wherein the controller (302) is configured to stop the application of microwave energy after a predetermined period sufficient to raise the temperature of the tissue structure； and wherein the microwave signal has a frequency in the range of: between about 4 GHz and about 10 GHz； or between 5 GHz and about 6.5 G
