FDTD simulation of 290 nm PAAO with gold nanoparticles: varying incidence angle, s-polarization, n=1

Version 2 has the same files as version 1 and some additional files. FDTD software: Lumerical (Ansys, version 2021 R2.3). Structure: aluminum (Palik) substrate; 290 nm thickness (h) aluminum oxide (Palik) layer with 35 nm diameter (RPo) cylindrical pores with 100 nm distance (D) between the pore centers (representing porous anodized aluminum oxide - PAAO); 60 nm diameter (RNP) gold (Johnson and Christy) nanoparticles placed directly above each pore. Refractive index of the surrounding medium (n): 1.0. Simulation region: from 300 nm below the substrate/PAAO interface to 1.3 µm above PAAO surface; x and y spans are equal to one period of the structure. Mesh override region: from 50 nm below the PAAO to 50 nm above the nanoparticles; 2 nm step size in each direction. Light source: BFAST plane wave light source; 500 nm above PAAO; varying (20° - 70° in steps of 5°) angle of incidence (ang); 300 nm – 1000 nm wavelength range; s-polarization (pol). Monitor (frequency domain field and power): 2D Z-normal; 1 µm above PAAO; results are in "_reflection.txt" files. Information in the file name: h - thickness of PAAO; pol - polarization; RNP - diameter of gold nanoparticles; RPo - diameter of pores; D - distance between pore centers; ang - angle of incidence; n - refractive index of surrounding medium. Files: (1) "_reflection.txt" - lambda(nm) (first column) - wavelength in nanometers; Y (second column) - T data from the monitor above the structure. (2) "_p0.log" - log file produced by the software while running the simulation. (3) ".fsp" - Lumerical software file containing the simulation project (license required to open these files). Consecutive numbering corresponds to the angles of incidence: 1 - 20°, 2 - 25°, 3 - 30°, 4 - 35°, 5 - 40°, 6 - 45°, 7 - 50°, 8 - 55°, 9 - 60°, 10 - 65°, 11 - 70°. (4) "Lumerical_Screenshots.pdf" - shows software screenshots for every object and its every property; red text is added to show which values are different for different simulations. (5) "Structure_Illustration.png" - a schematic of modeled structure. (6) "290nm-Spol_varying-angle.jpg" - a preview of data from "_reflection.txt" files.
