An LLM read a pencil sketch, built antenna models, and ran the simulation

A ham radio operator had a frontier LLM read his pencil sketch of an antenna, build NEC models from it, test and iterate on numerical stability until the approximation held together, and then run a real simulation that answered his questions. He uses the same approach for SPICE circuit simulation.

How it works

  1. He shows the LLM his pencil sketch
  2. The LLM builds NEC antenna models from the sketch
  3. It tests numerical stability and iterates until the approximation is good
  4. It runs a real simulation that answers his questions

Why it’s worth knowing

The input was a hand drawn sketch. The agent turned it into working simulation models and ran them, a job that used to be a multi day manual chore.
