Abstract This paper proposes the first experimental demonstration of a pseudo-anapole-based cylindrical electromagnetic cloaking scheme. The pseudo-anapole state is excited by arranging split-ring resonators around a cylindrical metallic target. We used the multipole scattering theory to identify the actual reason behind the cloaking operation. Pseudo anapole condition is characterized by the scattering minima from toroidal and electric dipole moments, and hence the metallic target is undetectable from backscattering measurements. The results are verified using full-wave simulation software and subsequently validated with backscattering measurements inside an anechoic chamber.
