|Abstract:||Large-area asymmetric split ring resonator (ASRR) arrays are fabricated by femtosecond laser microlens array lithography. The double square ASRR consists of two gaps at the outer edge. The resonance properties of this ASRR under structural symmetry breaking conditions are investigated in the terahertz region by changing gap size at one side. The resonance of the ASRR shows blueshift from 0.85 to 0.98 THz when the one gap size increases from 2 to 14 μm. Numerical simulations reveal that the electric field enhancement at the fixed gap increases from 152 to 206 times as the degree of asymmetry increases. © 2010 American Institute of Physics.|
