FDTD Studio play online

FDTD studio is a fully functional one dimensional Finite Difference Time Domain solver (FDTD solver) to simulate light wave propagation in various structures.
Unlike ray optics, this app treats light as wave which makes it possible to simulate devices based on wave interference such as distributed Bragg reflectors, anti-reflection coatings and many more.
The electromagnetic wave source in the app can be tuned to any desired frequency and wavelength range from ultra-violet to visible and far-infrared.
Through this app, you can deeply understand wave nature of light and study various phenomena such as thin-film interference, Bragg reflection and
Main Features of the app include:
-Simple and straightforward structure definition through adding infinite number of layers
-Fully tunable electromagnetic source from ultra-violet to far-infrared
-Simple Incorporation of light attenuation through non zero conductivity for any layer
-Complete set of boundary conditions: reflecting, absorbing and perfectly matched layers
-Dipole and total-field scattered-field (TFSF) source
-Fully functional transmission and reflection monitors with desired frequency resolution
-Lots of tutorials and carefully prepared help for all the features of the app
