الملخص	Plasmonic resonance refers to the collective oscillation of free electrons in metallic nanostructures that interact strongly with light, resulting in dramatic enhancements of electric fields, absorption, and scattering. First discovered by Kretschmann and Raether in 1968, plasmonic resonance is now central to nanophotonics, enabling applications from biosensing to photothermal therapy and advanced optical devices with subwavelength control.	Rigorous Coupled-Wave Analysis is a semi-analytical computational method for solving Maxwell's equations in periodic structures such as diffraction gratings and photonic crystals. Developed by Moharam and Gaylord in 1981, RCWA expands the electromagnetic fields in each periodic region into Fourier series and couples the fields at interfaces, enabling accurate and efficient simulation of light diffraction, resonances, and wave propagation in structured media.
