Designing a nonscattering cylindrical structure

Abstract

We consider how an ideally conducting circular cylinder can be transformed into a body that does not scatter the field of a plane TE-polarized wave in a certain frequency range. The transformation is accomplished by using an appropriate system of resonators and narrow longitudinal slits in the cylindrical body (a “transparent” body synthesis problem). Sufficient conditions for the solvability of the synthesis problem are derived. The synthesis problem is solved numerically for a number of primary field frequencies, and the frequency dependence of the decay coefficient is obtained.
