Design of new dual-band left-handed material based on mirror “giant” shape

摘要

In order to achieve “double negative”, at the same time can also achieve dual operating frequency band, multi-operating frequency band and extended operating frequency range in the same structure. We proposed a mirror “giant” shape structure, the structure is a one-sided integrated electromagnetic resonator on the dielectric plate forming a left-handed unit, and through the software simulation and theoretical analysis to extract effective electromagnetic parameters, confirming the “double negative” and dual band characteristics of this structure. Which provides important reference for the design and wide application of multiband, low-loss microwave left-handed materials.
