I have encouraged a professor at my alma mater, Rose Hulman Institute of Technology, to quote on the desired EM modeling for LPP fusion. I have some experience in electrical power, and one thing that haunts a pulsed power system are the voltage reflections generated at terminations and devices. These are usually controlled by voltage breakdown devices which allow some energy to leak away in an arc-over. This is one of the fear-inducing factors in all the EMP conspiracy theories.
