IE3D is a moment-based electromagnetic field simulation tool based on full-wave analysis, which can solve the current distribution problem of three-dimensional metal structures in multi-layer media environment. The so-called full-wave analysis establishes the integral equation by the boundary conditions of each interface and the dyadic Green's function in the layered medium, and then derives the impedance matrix and the excitation matrix to obtain the current coefficient and solve the Maxwell equations, thereby solving the electromagnetic wave radiation effect. And other issues. The simulation results include S-, Y-, Z-parameters, VWSR, RLC equivalent circuit, current distribution, near-field distribution and radiation pattern, directionality, efficiency and so on.
IE3D is a very useful tool for microwave/millimeter wave integrated circuits (MMICs), RF printed circuit circuits, microstrip antennas, wire antennas and other forms of RF antennas, filters, IC internal connections and high speed digital circuit packages. . It has the following characteristics:
1. Based on MS-WINDOWS, mouse-driven graphical interface;
2. Modeling a three-dimensional metal structure in a multilayer medium;
3. Efficient, highly accurate and flexible simulation engine;
4. Create flat and three-dimensional metal structures using sketches, intrinsic libraries, and powerful editing tools;
5. Automatically generate a non-uniform rectangular, triangular mesh suitable for the geometry being analyzed;
6. With the characteristics of automatic edge grid, so that beginners get accurate professional results;
7. Modeling structures with infinite and finite ground planes;
8. Accurate and flexible circuit parameter extraction for local de-embedding and differential feed design;
9. Can accurately model metal thickness, extremely thin medium, lossy medium, etc.;
10. Automatic and flexible electromagnetic field optimization function with reliable and efficient optimizer;
11. Hybrid electromagnetic simulation and node analysis for large scale integrated circuits;
12. Magnetic flow modeling of CPW (coplanar microstrip line) structure and caliber coupling structure;
13. Adaptive function, using less simulation, can quickly and accurately obtain broadband analysis results;
14. Simulate and explore the excitation function to allow monitoring of the power distribution of the antenna array in the feed network;
15. Using the symmetric matrix solver, the differential matrix solver and the iterative matrix solver to improve the simulation efficiency;
16. Display S-, Y-, Z-parameters, VSWR and radiation patterns in Cartesian and Smith charts;
17. Calculation of radiation parameters, including directionality, efficiency and radiated power;
18. Display current distribution, radiation pattern and near-field distribution in two dimensions and three dimensions.
