【Abstract】 Based on the concept of spoof surface plasmon polaritons,an ultra-thin microwave sensor for nondestructive testing of composite materials is proposed in this paper,which has a larger sensing area than the traditional microwave sensor. The characteristics of spoof surface plasmon polaritons waveguide to support long-distance bending transmission are applied to the design of the sensor. Taking two kinds of bending shape sensor as an example,the corresponding S parameters are obtained through simulation to analyze the bending loss. By analyzing the electric field distribution on the surface of the sensor,the mechanism of the sensor for nondestructive testing of composite materials is studied. Finally,the validity of the sensor is verified by experiment.更多还原
