Figure Lengend Snippet: Numerical results from the COMSOL Multiphysics simulation. Distance between the two monopole point sources = d. ( a ) Results obtained with lens thickness h = 40 mm; without the lens, the data were scaled by adding 22 dB to the original data. ( b ) Results obtained with lens thickness h = 80 mm; without the lens, the data were scaled by adding 67 dB to the original data. ( c ) Results obtained with lens thickness h = 212 mm; without the lens, the data were scaled by adding 125 dB to the original data. ( d ) Data obtained with a single monopole source using metalenses with thicknesses h = 40, 80, and 212 mm. Data with lens thicknesses h = 80 and 212 mm were scaled by adding 8 and 15 dB, respectively. R1, R2, and R3 are the ranges for the full width at half maximum (FWHM) 3 dB below the peak.
