It calculates the electromagnetic field as a function of time and space in a given indexstructure in response to a given electromagnetic excitation. FullwAVE is ideal for studying the propagation of light in awide variety of photonic structuresFullWAvE is fully integrated into the rSofl CAd environment which allows the user to define the material propertiesand structural geometry of a photonic device. FullWAVE can accurately model both dielectric and magnetic materials, aswell as anisotropic, dispersive, and non-linear materials. It also can utilize a computing cluster in order to achieve bothlarger and faster simulationsTo use FullWAVE effectively, it is critical to have a working knowledge of the rSoft Cad interface. The cad tool isdescribed in full in the RSoft Cad manual, which is included in the FullwavE package. The reader is stronglyencouraged to study the Cad manual before reading beyond Chapter 3 of this manualAs a member of the RSoft Photonics Suite, FullwAVE is designed to work with rSoft's other passive device simulationmodules. This modular approach to the design and simulation of photonic devices is one of rSoft's Photonic Suitesgreatest strengths. Each program in the suite is designed to "play nice "with the other programs, creating an environmentin which data can be shared between the modules. Virtually all the input and output files are in a simple ascii textformat, which allows even greater user control over program operation as well as third-party programs to be integratedinto the suiteWhile the rSoft Photonics Suite is designed to be used via the GUI(Graphical User Interface), command line operationis also possible. This, coupled with the modularity of the Suite, allows for complex scripting capability. The Suite is notlimited to a single scripting language, but rather uses the native scripting language of your operating system. Forexample, Windows users can use dos batch files, while Unix users can use bash scripts. Additionally, users familiarwith languages such as Perl, Python, C, or C++ can create custom scripts in these languages The rSoft photonics Suiteprovides the best of both worlds: it allows for simulations to be performed via the GUI, and for complicated customsimulations to be performed via a script. New and advanced users alike are able to realize the full power of the suite
