#antenna #NEC #FDTD #electromagnetics

Of the many antenna simulation computational techniques in use today, we compare two of the most popular methods: Moment of Methods (MoM) as used in Numerical Electromagnetics Code (NEC) and Finite-Difference Time-Domain (FDTD).

Shown is simulation of a five-element Yagi-Uda 20m beam.

Thank you for a clear, concise comparison of the two methods. I've been playing with Ansoft HFSS which works more along the lines of FDTD technique, but it also requires longer run-times than MOM like used in 4NEC2.

Are you available to design 2 co-phase 2 element Delta loop wire beams for under my 16’ tall bay house on stilts? I need modeling done before I build. If interested, contact me via my YouTube channel contact. I will pay you of coarse for your time. 73’s George
