NRI-TL superlens unit cell.
NRI-TL superlens dispersion characteristics determined using the equivalent-circuit theory (curves) and full-wave finite-element-method simulation data obtained using Ansoft’s HFSS (circles): (a) phase shift per unit cell , (b) relative effective material parameters (dashed blue curve), (dotted green curve). (i) The Veselago-Pendry superlensing condition achieved at , (ii) resonance in at , and (iii) resonance in at .
Fabricated Veselago-Pendry NRI-TL superlens (, ). Inset: unit cells on layers loaded using surface-mount elements.
Measured normalized transverse field profiles at the focal plane vs frequency from (black curve represents the continuous half-power contour). Super-resolution evident at 2.40 and .
Measured transverse field profiles at (red solid curve) and (blue dashed curve) normalized to the maximum field value of the former.
