(a–d) The electric field distributions of the TJ formed by a BDS-coated dielectric sphere with R = 500 μm and dDS = 1.5 μm at Fermi energy of \(E_{F}\) = 55 meV for input angles of (a) 5°, (b) 25°, (c) 40° and (d) 60° for the TE case. (e–h) The TM counterparts of (a–d). The dashed circles show the boundary of the sphere. (i, j) The emergence angle and intensity of the TJ, respectively, as a function of the uniform beam rotation angle.
