Experimental Realization of Dual-Polarized Cylindrical Shaped Microwave Network Cloak

In this paper, the experimental verification on the performance of a dual-polarized microwave network based invisibility cloak is demonstrated. A microstrip slotted square patch is used as the unit cell of the cylindrical shaped cloak to achieve the invisibility effects at around 1.35 GHz and 1.67 GHz for transverse electric (TE) and transverse magnetic (TM) polarization states of the incident wave, respectively. The thickness of the proposed cloak design is
$\mathbf{0.012}\lambda$
and
$\mathbf{0.015}\lambda$
at 1.35 GHz and 1.67 GHz, respectively. The fabricated cloak consisting of
$\mathbf{13} \times \mathbf{5}$
unit cells of the slotted patch shows a normalized total scattering cross-section of 0.25 and 0.22 for TE and TM polarized incident waves, respectively.
