Product Name: FIDELITY: FDTD-Based EM Simulator

Product Description

About FIDELITY

FIDELITY is a FDTD (Finite-Difference Time-Domain) based Full-3D EM Simulator for modeling microwave circuits, components, and antenna, wireless/RF antennas, EMC and EMI structures, and other high-speed and high-frequency circuitry.

FIDELITY's Features

1. Non-uniform mesh for modeling planar and 3D structures with complicated dielectric configuration. Users are not limited to the mesh. The mesh can be adjusted to fit a geometry. 2. Accept planar, 3D and non-isotropic dielectric materials. 3. MS-Windows based, menu-driven graphic interface for interactive construction of planar and 3D structures as objects. Strong geometry editing and checking capability. 4. Multiple 2D and 3D views for better visual understanding of the structures in editing. 5. Radiating boundary conditions modeled as various absorbing boundary conditions including PML. Antenna structures can be modeled efficiently and accurately. 6. Automatic generation of non-uniform mesh and meshing independent geometry entry allows users to enter a structure once for different meshing schemes. The mesh for the geometry can be changed anytime before a structure is simulated. Change of mesh does not need re-entry of the geometry. 7. Pre-defined coaxial port, microstrip port, rectangular waveguide port, circular waveguide port and user-defined port allow hassle-free port definition. 8. Integrated preprocessing and post-processing. 9. Automatic s-parameter extraction allows accurate and fast calculation of s-parameters and input impedance. The package includes a network simulator for flexible post-processing of s-parameters and impedance parameters. 10. Radiation pattern calculation. Calculation of antenna directivity, gain, efficiency and other parameters. The package includes the PatternView for pattern displays and comparison. 11. 3D electric field, magnetic field and Poynting vector display with slicing capability. 12. One simulation yields results in a wide frequency spectrum. 13. Plane-wave excitation for scattering and shielding investigation. 14. Complete SAR-calculation and display: Colorful display of 3D SAR-distribution and Cartesian display of SAR-distribution. Users can control the input power level and can access the parameters such as absorbed power and radiated power. 15. Frequency-domain field calculation and display. 16. Automatic time signals convergence detection: Users do not need to guess how many time-steps they need to run simulations. The program automatically detects the convergence and stop a simulation at convergence. 17. Time signal convergence acceleration reduces the time marching steps significantly. The following time signals from a patch antenna indicate the difference. Without loosing accuracy, the simulation time is shortened by a factor of 20. 18. Localized ports allow users to extract s-parameters in a small region. It saves a large amount of space and simulation time. It also allows simulation of highly packed structures with lumped elements. 19. Frequency-independent human head models:
