The conductivity distribution was reconstructed from the pressure distribution on the spherical detection surface with the time reversal method. 本研究构建三维柱状线圈和二层同心球模型以模拟成像物理环境,借助有限元软件ANSYS分析瞬态电磁场,并根据分析结果,进行MAT-MI正问题声场计算,应用时间反演法进行电导率的...
Time-reversed equations There are a number of systems that can detect partial discharges, but they aren't very effective in pinpointing where they originate. "With our method, engineers can locate the source of a partial discharge and act quickly to solve the problem," says Hamid Reza Karami,...
We then extend the source time reversal method, originally developed for acoustic waves, to an elastic system of waves. Additionally, we present a fast reconstruction implementation for large data sets. This is especially useful in the elastic case, in which the numerical cost is higher than in...

We perform theoretical analysis of the method of field focusing in a randomly inhomogeneous waveguide using reradiation of the received signal with time reversal. The simplest case where point sources and receivers are used for emission and reception is considered. As an example, the waveguide is ...
