Ie3d V15 127 New - Zeland

Zeland IE3D v15.127 marks a significant milestone in the evolution of electromagnetic (EM) simulation, specifically tailored for the design and optimization of 3D microstrip antennas, microwave circuits, and high-speed PCBs. This version builds upon the robust foundation of the Method of Moments (MoM) algorithm, which has long been the industry standard for planar and 3D EM simulation. Core Capabilities of IE3D v15.127
