A headline feature in “new” v15.127 is the . Large antenna arrays (e.g., 256+ elements) are notoriously difficult to simulate with full-wave methods. This new module uses a combination of unit-cell MoM simulations and array scanning methods to synthesize the full finite array response without brute-force simulation. The result? Simulating a 128-element phased array now takes minutes instead of days, with an error margin under 0.5 dB for mutual coupling. zeland ie3d v15 127 new
