Abstract
Electrical single-negative material A and magnetic single-negative material B are used to constitute a symmetrical one-dimensional photonic crystal. Numerical calculation results indicate that a tunneling mode will appear in its band gap. With material layers increasing, the width of the tunneling mode narrows sharply, but its position remains unchanged. The position and width of the tunneling model are not sensitive to the incident angle. With the geometry thickness of the material reducing, the position of the tunneling mode is blue-shifted, but its width remains unchanged. With μA and εB increasing, the location of tunneling mode is red-shifted and the width decreases. Using the properties of the tunneling mode, it is possible to realise dynamic regulation for electromagnetic wave propagation.
