Dynamic Volume Equivalent SBR Method for Electromagnetic Scattering of Targets Moving on the Sea

IEEE Transactions on Antennas and Propagation, 2023
To solve the scattering of targets moving on the sea, based on the volume equivalent shooting and bouncing ray (VESBR) method, a method named dynamic VESBR (DVESBR) is proposed. Because of the motion of the targets and the variation in the sea, the whole

Dynamic Modeling for Electromagnetic Scattering by Moving-Boundary Objects

2019 IEEE International Conference on Computational Electromagnetics (ICCEM), 2019
The objects or structures in electromagnetic (EM) problems usually have a fixed geometric shape or boundary and the geometric discretization is assumed to be unchanged in numerical solutions. However, as flexible electronic materials appear and could be more widely applied to the manufacture of electronic devices and systems, such an assumption may not
