Magnetic field intensity and displacement current. A map of the normalized total magnetic field intensity distribution (color bar) and displacement current (JD) (arrows) along the plane β: (a) at a 2,140-nm resonance wavelength for trigonal Bi2Se3 and (b) at a 1,770-nm resonance wavelength for orthorhombic Bi2Se3, where the light source is p polarization at normal incidence angle.
