“…RCWA is a widely used method and has evolved to be a reliable tool for calculating the diffraction efficiencies of layered periodic nanostructures made of dielectric and/or metallic gratings [27][28][29][30][31][32]. The procedure for calculating the local energy density distribution and the integrated energy storage in gratings is described in the following.…”

The processes of storage and dissipation of electromagnetic energy in nanostructures depend on both the material properties and the geometry. In this paper, the distributions of local energy density and power dissipation in nanogratings are investigated using the rigorous coupled-wave analysis. It is demonstrated that the enhancement of absorption is accompanied by the enhancement of energy storage both for material at the resonance of its dielectric function described by the classical Lorentz oscillator and for nanostructures at the resonance induced by its geometric arrangement. The appearance of strong local electric field in nanogratings at the geometry-induced resonance is directly related to the maximum electric energy storage. Analysis of the local energy storage and dissipation can also help gain a better understanding of the global energy storage and dissipation in nanostructures for photovoltaic and heat transfer applications.

“…This enables one to access new physical regimes and to discover and systematically analyze new physical phenomena in thermal transfer physics. Even tough thermal emission from periodic structures to air is investigated in several references [21,22], to our knowledge this is the first time, such a theory is developed for rigorously obtaining thermal transfer between nano-structured periodic materials and a planar structure in the near field regime. The RCWA technique together with the possible use of symmetries in the systems boosts the numerical efficiency compared with the simulations that has been done for calculation of thermal transfer between grating structures using the FDTD method, recently [23].…”

This paper provides a method based on rigorous coupled wave analysis for the calculation of the radiative thermal conductance between a layer that is patterned with arbitrary, periodically repeating features and a planar substrate. This method is applied to study the transfer from an array of beams with a rectangular cross section. The impact of the structure size and spacing on the thermal conductance are investigated. These calculations are compared to an effective medium theory, which becomes increasingly accurate as the structure sizes fall well below the relevant resonance wavelengths of materials and structures. Moreover, comparisons are made with a modified proximity approximation and the far-field approximation, which become valid for small and large spacings, respectively. Results show that new levels of control over the magnitude and spectral contributions to thermal conductance can be achieved with corrugated structures relative to planar ones. Specifically, we show for SiC arrays with rectangular cross sections and with the same filling fraction that the use of a smaller periodicity leads to a lowered far-field thermal transfer and an increased near-field thermal transfer.
