  1. ; (, 2024 IEEE International Symposium on Antennas and Propagation)
    A penetrable tensorial metasurface on a grounded dielectric shell is presented for 3-D spherical invisibility cloaking. The spatially modulated impedance surface transforms the incident plane wave into a surface wave on the lit side and carries the power to the shadow side. Power is continuously released as a leaky wave with a wavefront consistent with the incident plane wave on the shadow side. A numerical design example for a four-wavelength-diameter conducting sphere is presented, and the cloaking effectiveness is validated by simulation.
