Fig. 4: Numerical confirmation of the all-angle reflectionless negative refraction (AREN).
From: All-angle reflectionless negative refraction with ideal photonic Weyl metamaterials
a Configuration for observing the AREN. Half of the top surface of the Weyl metamaterial is covered by a PEC layer, while the other half is covered by a PMC layer. A point source (electric dipole in z direction) is placed at the PEC/metamaterial interface. b, c Imaging due to the AREN. The distributions of electric field Re(Ez) and magnitude \(\left| {{{\boldsymbol{E}}}} \right|\) at the frequency 25GHz are plotted respectively. d, e The distribution of the electric field and the magnitude obtained by replacing the PEC and PMC layers with two different dielectric layers (∈1 = −10 and ∈2 = −0.01)
