We present a design for a sub-wavelength hole array (SHA) decorated with an electric resonance ring (ERR) to realize angle-insensitive extraordinary optical transmission (EOT) at 9.7 mu m. A net electric resonance in the whole MM plane, induced by the counter-circulating LC loops in each MM unit-cell, is proposed to have the primary responsibility for the EOT. By tuning the carrier density of an added doped-semiconductor that participates in the in-plane LC resonance, dynamic EOT manipulation and an electric-control turn-on/off function is obtained in our MM.
