ДЄppropriate design of metasurfaces requires understanding of transmission or reflection characteristics of individual antennas. Recently efforts are focused on active tunabilityВ as well as largescale manufacturing of dielectric metasurfaces for practical applications. Simultaneous control of multiple parameters is also possibleВ .

Many types of antennas have been developed to control wave parameters such as amplitude, phase and frequency. Scattering properties of dielectric antennas are determined by multipole resonances that incident light induces inside antennas the resonances can be tailored by modifying the geometry of antennasВ . Reflective plasmonic metasurfaces of metalвЂ“insulatorвЂ“metal configurations exploit FabryвЂ“Perot cavity effects, and therefore can achieve very high modulation efficiency in the visible spectrum however, the modulation efficiency of transmissive plasmonic metasurfaces is usually very low compared with conventional refractive optical elements.Дielectric metasurfaces have high modulation efficiency for both reflective and transmissive types. Plasmonic metasurfaces exploit surface plasmons, which are collective electron oscillations at the interface between conductors and dielectrics. Metasurfaces can be classified as plasmonic or dielectric, according to the nature of the materialВ .

Due to those advantages, many promising applications have been demonstrated using metasurfaces such as ultrathin lensesВ , hologramsВ ,, , structural colorsВ ,, and skin cloaksВ . In contrast, metasurfaces in which thickness is comparable to the operating wavelength can perform the same functions because tiny antennas of metasurfaces can efficiently interact with incident light. Conventional optical components such as lenses control light by exploiting refraction, so the final devices are usually bulky and heavy. Metasurfaces that consist of subwavelength optical antenna arrays have shown exceptional capabilities as ultrathin flat optical devicesВ . Diffraction from periodic structures can be fully described by the total scattering matrix and total coupling coefficients.ДЄdditional comments including restrictions and unusual features: MAXIM builds on several open-source Python packages including PySide2, Numpy, Scipy, Pandas, Matplotlib and Pyinstaller. Total coupling coefficients can be also calculated using the extended Redheffer star product this ability is a major advantage of the extended scattering matrix method. In the case of a multilayered structure, a total scattering matrix can be obtained using the Redheffer star product, which interconnects scattering matrices of each layer. Appropriate boundary conditions at the interface of a single structure layer enable development of an eigenvalue equation for which the solution gives a scattering matrix of the layer, and the coupling coefficients within it.

According to BlochвЂ™s theorem, diffracted waves from periodic structures can be represented as a truncated Fourier series in which the primitive reciprocal vector is the same as that of periodic structures. Solution method: Rigorous coupled-wave analysis associated with an extended scattering matrix method.

The main purpose of this software is to calculate complex transmission and reflection coefficients of diffracted waves from dielectric metasurfaces that are composed of arrays of subwavelength antennas. Wave parameters such as amplitude and phase of diffracted waves are modulated depending on the structure configuration. Diffraction occurs as a propagating electromagnetic wave meets periodically-structured arrays of materials that have different refractive indices. Nature of problem: Time-harmonic electromagnetic wave simulations on multilayered periodic structures composed of isotropic materials.
