a Illustration of the unit cell of the designed MM consisting of different alumina layers spaced by foam. b Picture of the fabricated sample with a unit cell and the measuring environment. c Simulated transmittance through the MM sample (solid lines and symbols) and an alumina slab of the same thickness (dashed lines) for TE (blue) and TM (red) polarizations as a function of the incident angle at 3.8 GHz. d Measured \({E}_{y}\) on the xz (upper) and yz (lower) planes at 3.8 GHz. The left, middle and right panel graphs denote the case of the MM sample, the case of free space and the case of the alumina sample, respectively. Scattered fields in the cases of the MM (left) and pure alumina (right) samples on the (e) xz and f yz planes on the source side
