Fig. 2. Design of effective self-dual MMs using dielectric multilayers.

Caption

a Illustration of a dielectric MM consisting of ABA multilayers. b Transmittance through N numbers of ABA units in air as a function of the incident angle θi for TE (blue) and TM (red) polarizations. c Wave impedances of free space (lines) and MM (dots) for TE and TM polarizations. d Band structures of the MM for TE (blue) and TM (red) modes. The black dashed line denotes the functioning frequency f a/c = 0.277 . e EFSs of TE (blue) and TM (red) modes at f a/c = 0.277 . f Angle of refraction θr at the interface between free space and MM as a function of the incident angle θi for TE (blue) and TM (red) polarizations.
