In order to evaluate scattering from hypersonic vehicles covered with the plasma efficiently, time domain volume shooting and bouncing rays (TDVSBR) is first introduced in this paper. The new method is applied to solve the transient electromagnetic scattering from complex targets, which combines with non-homogeneous dielectric and perfect electric conducting (PEC) bodies. To simplify the problem, objects are discretized into tetrahedrons with different electromagnetic parameters. Then the reflection and transmission coefficients can be obtained by using theory of electromagnetic waves propagation in lossy medium. After that, we simulate the reflection and transmission of rays in different media. At last, the scattered fields or radiation are solved by the last exiting ray from the target. Compared with frequency-domain methods, time-domain methods can obtain the wideband RCS efficiently. Several numerical results are given to demonstrate the high efficiency and accuracy of this proposed scheme.

One of the most remarkable features of surface plasmon polaritons (SPPs) is their usefulness for sensing. In this paper, we introduce a spoof SPP sensor consisting of a transmission line with a rectangular groove array. We investigated its dispersion relation and verified the broadband transmission characteristics of its SPP mode. A sensing model with spoof SPPs has been developed and a prototype fabricated. Three analytes with different permittivity were introduced into the model and prototype — edible oil, glycerol, and water — and the results compared to those obtained with air. The results of simulation and measurement show that the sensor is extremely sensitive to the permittivity of a liquid. The results indicate that spoof SPP sensors have important potential applications in industrial processing, food safety, and environmental monitoring.
