Electromagnetic Cancellation Based on the Equivalence Principle

Electromagnetic cancellation is one of the methods to realize electromagnetic stealth. In this paper, according to the equivalence principle, we eliminate the scattering field of the object by superimposing magnetic and electric current densities outside the boundary of the object. This idea is similar to sound cancellation in acoustics. However, in most cases, we only care about the scattered field in a specific direction. Therefore, we simplify the equivalent magnetic and electric current of the closed surface. Finally, we analyze it through simulation.
