OMNISIM is software that analyzes photonic devices/grating structures using solvers such as FDTD/FETD/RCWA.
A unique combination of FDTD and FETD simulators OmniSim is the only software package to include both FDTD and FETD engines. This combination allows you to get the best of both worlds: FDTD for quick approximate simulations and FETD for higher accuracy, or even just to check your FDTD calculations with an alternative method.
FIMMWAVE is software that allows for easy mode analysis of complex waveguide and fiber structures using a waveguide mode solver.
A large number of complementary solvers ・FIMMWAVE contains a variety of robust and computationally efficient solvers optimised for such structures. ・FIMMWAVE combines:methods based on semi-analytic techniques, which allow to tackle efficiently problems with strong variations in refractive index, thin layers, etc. ・numerical methods such as finite elements (FEM) or finite differences (FDM), providing robust solutions to arbitrary problems.
Weather and optical simulations made possible by Ontar.
Ontar is software that can simulate atmospheric radiation transfer, spectral analysis, and LIDAR design with high precision. 【Features】 ■ PcModWin6 can perform radiation transfer calculations (transmittance, radiance, scattered radiance, solar/moon illumination) of MODTRAN 6 through GUI operations only. ■ By selecting the line-by-line (LBL) mode of MODTRAN, high-resolution spectral analysis at the level of 0.001 cm⁻¹ can be conducted. ■ PcModWin6 automatically generates input files in both traditional tape format and JSON format, preventing errors from manual input. ■ HITRAN-PC 5.0 calculates gas absorption spectra rapidly (up to about 25 times faster) using line data from HITRAN 2012 and GEISA. ■ HITRAN-PC 5.0 allows real-time toggling of molecules and isotopes, enabling immediate visualization of absorption contributions. *For more details, please refer to the related links or feel free to contact us.
