The beam-envelope method solves only for the slowly varying electric field envelope by means of mathematical trickery that separates out the quickly varying part. After the solution for the slowly varying part is obtained by means of a computational method such as, for example, the finite-element method, the full-wave field is obtained by ... Electrical cables are classified by parameters such as impedance and power attenuation. In this blog post, we consider a case for which analytic solutions exist: a coaxial cable. We will show you how to compute the cable parameters from a COMSOL Multiphysics simulation of the electromagnetic fields.
