In this paper, polarization insensitive metamaterial absorber using sunflower shaped unit cell is proposed. The performance of the proposed absorber was dcmonstared with 3D full-wave EM solver under normal incidence for TE and TM polarization modes. Due to the symmetric geometry of the sunflower shaped unit cell, the proposed absorber provides a high level of absorptivity, about %90, for both TE and TM modes at 11.9 Gliz. To enhance the absorptivity, we then created a hollow at the center of the proposed unit cell. The later design resonates at 11.7 Ghz, and provides perfect absorption for both polarization modes.
