## A Numerical Electromagnetic Solver Using Duality

In the previous insights article (How to Use Duality in Computational Electromagnetic Problems), I covered some uniqueness theorems for the Riemann-Silberstein vector, ##F=E+iB##, for time-harmonic fields. We showed that the boundary value, ##f##, completely determines the vector field throughout the volume. In this article, I’d like to step through constructing a numerical algorithm for finding…
