HiPhi boundary input from EStat

Many improvements to our programs follow from user suggestions. My consulting projects often provide motivations for new features. I am presently working on a simulation of a large cylindrical vacuum insulator for a pulsed-electron-beam injector. The issue is whether non-symmetrical flaws in the insulator surface will cause substantial field perturbations. I started by creating a 2D [...]

Static fields in a dynamic code

The Aether code (scheduled for release on September 30) culminates 12 years of my research on fast numerical methods for electrodynamics. The frequency-domain techniques were adapted from a program called RedWall that I developed for NIST. The time-domain strategies were tested in EMP3.

The application of Aether to pulsed-power devices is particularly interesting to me because I [...]

Simulating a pulsed-power system with Aether

The development of Aether continues on schedule for release in September. Capabilities for time-domain simulations are complete are we are creating several examples for the tutorial manual. In this example, the full three-dimensional capabilities of the code are used to characterize a pulsed power system. The goal is to design a dummy load to test a [...]
