Geometry for the resonance excitations of NWGMs in a layered superconductor slab of thickness sandwiched between two dielectric prisms. The latter are separated from the layered superconductor slab by two vacuum gaps of thickness . An electromagnetic wave with angle o fincidence can excite SJPWs that satisfy the following resonance condition: . Here and are the wave-vectors of the incident and reflected waves associated with the magnetic field amplitudes and . The resonance excitation of SJPWs by the incident wave produces a strong suppression of the reflected wave. This method for producing surface waves is known as the “attenuated-total-reflection” method.
The dependence of the reflectivity on the incidence angle for the two different vacuum gap widths: (dashed curve) and (solid curve). Thus the minimum value of the reflectivity for the second case equals to zero. The normalized incident wave amplitude is . Other parameters are: , , , , , , .
The dependence of the reflectivity on the magnetic field amplitudes for the incidence angle . The other parameters are the same as in Fig. 2.
The magnetic field distribution for the non-resonant case, , the vacuum gap widths . Other parameters are the same as in Fig. 3.
The magnetic field distribution for the resonant case, . Other parameters are the same as in Fig. 4.
