Frequency optimization of permeability metamaterial for enhanced resolution.

We analyze and optimize the performance of unconventional negative permeability (µ) metamaterial and demonstrate its ability to focus and restore the decaying Fourier harmonics (FH) in microwave regime operating frequencies. We show that multiple real µr' and imaginary µr'' values of µr at same or multiple operating frequencies for a resonant type of -µ metamaterial could not exhibit finest resolution at the region of interest (ROI), unless and until the distance of the source plane with respect to metamaterial and ROI could be re-optimized in accordance with µr' and µr'' of µr. Using the variable parameters to enhance the resolution limit of -µ metamaterial, we optimize the metamaterial's configuration for maximum propagation field absorption and regeneration of decaying FH at ROI. The optimization of the test bed that contains the source plane, -µ metamaterial, and ROI followed by the regeneration of the decaying FH from the source plane at the surface of the material, yielded a high image resolution at ROI.
