Work as g1For 205 nanometers, g2When being 215 nanometers, change the transparent resonance dress of the super surface class electromagnetically induced of all dielectric respectively The different parameters for setting structure study it and change the influence to class EIT result.It keeps the other parameters of structure constant first, only changes The size for becoming the length a of upper transverse part 11, middle transverse part 13 and inferior transverse part 15, shows the parameter as length a through result of finite element When variation range is between 460~700 nanometers, since the sensitivity that the resonance frequency of Ming Mo and dark mould changes parameter a is basic Unanimously, i.e., detuning very little between the two keeps the effect of class EIT after interaction.Fig. 6 show selection length a=respectively At 460,600,700 nanometers, the transmittance curve figure that is obtained through FEM calculation.From fig. 6 it can be seen that with length a's Increase, class EIT transmission peak wavelength will appear Red Shift Phenomena, but class EIT transparency window effect remains unchanged, transmitance be maintained at 97% with On.
Similarly, it keeps structure other parameters constant, only changes the size of 1 height h of resonant element, through result of finite element Show when the parameter variation range of height h is between 180~300 nanometers, since the resonance frequency of Ming Mo and dark mould is to parameter The sensitivity of h variation is almost the same, i.e., detuning very little between the two keeps the effect of class EIT after interaction.Shown in Fig. 7 To choose height h=180 respectively, at 250,300 nanometers, the transmittance curve figure that is obtained through FEM calculation.As shown in Figure 7, With the increase of 1 height h of resonant element, class EIT transmission peak wavelength will appear Red Shift Phenomena, but class EIT transparency window effect is kept not Become, transmitance is still maintained at 97% or more.
Meanwhile we also calculate and are keeping structure other parameters constant, only change upper transverse part 11, middle transverse part 13, lower cross Corresponding transmittance curve figure when portion 15, upper vertical portion 12 and the width b in lower vertical portion 14.Show to work as width through result of finite element When spending the parameter variation range of b between 110~130 nanometers, width b is changed due to the resonance frequency of Ming Mo and dark mould spirit Sensitivity is almost the same, i.e., detuning very little between the two, and the effect of class EIT is kept after interaction.Fig. 8 is shown to be chosen respectively Width b=110, at 120,130 nanometers, the transmittance curve figure that is obtained through FEM calculation.It can be obtained by Fig. 8, with width b's Increase, class EIT transmission peak wavelength will appear Red Shift Phenomena, but class EIT transparency window effect remains unchanged, transmitance be maintained at 97% with On, the conclusion that conclusion obtains when changing with other parameters is consistent.
In conclusion the super transparent resonance device of surface class electromagnetically induced of all dielectric has robustness, that is, work as structural parameters When changing in a big way, class EIT will not influence as a result, comparing other transparent resonance devices of class electromagnetically induced, which will Be conducive to device fabrication and practical implementation.In addition, resonance device of the present invention can be used for the wave bands such as Terahertz, microwave.
