, to achieve compact radiating structures that meet specific bandwidth needs for 5G, satellite, or microwave communications. Design Flexibility
IE3D (Integral Equation in 3 Dimensions) is a full-wave electromagnetic simulator based on the method of moments (MoM), a technique for solving Maxwell's equations directly. Originally developed by in 1993, it became known for its ability to model complex, true 3D structures like conical vias, spiral inductors, wire bonds, and helical antennas . This paved the way for the design of antennas (patch, slot, PIFA), RF circuits, MMICs, and high-speed PCBs, where accurate EM modeling is critical.

We tested against the previous build (v15.110) on three standard benchmarks.
: The software inherently handles radiation into free space without requiring artificial radiation-absorbing boundary conditions. , to achieve compact radiating structures that meet
Though built with a planar core, IE3D models complex multi-dimensional elements like wire bonds, conical vias, helix structures, and finite metal thicknesses. Rather than treating trace thickness as a mathematical correction factor for loss calculations, IE3D maps currents across all four vertical and horizontal edges of a conductor. This provides highly accurate results when designing tightly coupled striplines and differential pairs. New Features and Enhancements in V15.127
The interface supports an interactive, polygon-based construction system for creating 3D structures. For more complex shapes, a provides pre-defined objects such as circles, rings, spheres, rectangular and circular spirals, and various types of vias and helices. Together, these features create a smooth and powerful design workflow, from initial concept to final verification.
