## 4 Conclusions  
In present work, we have studied the frequency dependences of the resonant optical response of anisotropic MoS\({}_{2}\) nanoparticles possessing several bright resonances at once in near-infrared region. The scattering cross section has been calculated and multipole decomposition has been fulfilled for various directions of irradiation of MoS\({}_{2}\) disks with a hole. It has been shown that the presence of several multipole resonances of the same order at once in a narrow spectral range is associated with the internal anisotropy of the material, which also affects the nonlocal optical properties of the disks. Using the results of numerical calculation of the dipole polarizabilities for a single MoS\({}_{2}\) disk, the parameters of the metasurface, supporting several QTM resonances at once in the narrow spectral range of the near-infrared region, have been tuned. Each QTM resonance is related to the excitation of bianisotropic response of a single disk and characterized by a dip in the reflection coefficient and enhancement of light transmission by the entire metasurface in a narrow spectral range. The use of orthogonal polarization of the incident wave leads to the disappearance of the electric-type bianisotropic response but causes the multiple bianisotropic magnetic-type responses responsible for the excitation of another multiresonance in the same spectral range. As a result, the switching of light reflection/transmission coefficient of the metasurface occurs, which can be used to design selective polarizing mirrors, optical switches, and routers with enhanced bandwidth. From a technical point of view, the designed metasurfaces can be fabricated by exfoliating individual flakes from transition metal dichalcogenide crystals and using their further processing by means of electron-beam lithography to form ordered arrays of nanoparticles.

Figure 5: (**a**) Dependences of reflection (R), transmission (T), and absorption (A) coefficients on the wavelength for the metasurface composed of MoS\({}_{2}\) disks irradiated by the wave with polarization oriented at angle \(\varphi=-38^{\circ}\) relative to the \(x\) axis. (**b**) Dependences of the reflection and transmission coefficients for parallel (\(\mathrm{R_{\parallel}}\), \(\mathrm{T_{\parallel}}\)) and perpendicular (\(\mathrm{R_{\perp}}\), \(\mathrm{T_{\perp}}\)) components of electric field on the wavelength for the metasurface irradiated by the wave with the polarization angle \(\varphi=-38^{\circ}\). (**c**) Angular dependences of total (R, T, A) and orthogonal (\(\mathrm{R_{\perp}}\), \(\mathrm{T_{\perp}}\)) reflection (R), transmission (T), and absorption (A) coefficients at the wavelength \(\lambda=1544\) nm. The parameters of the metasurface correspond to Figure 4.
