He is responsible for the strategic direction of the company's electrical and electronics products christian louboutin the High Frequency Structure Simulator (HFSS) finite-element simulator. Dr. Williams is an expert in the application of three-dimensional (3D) electromagnetic (EM) field simulation to the design of antennas, microwave components, and highspeed electronics. He has over 20 years of experience in the fields of electromagnetics and communications engineering and has published numerous technical papers on the subject.LW: Lab-based measurements have their place; simulations have their place. It's not an either/or decision. Engineers will always perform both. Of course, I Christian Louboutin Sandals strongly in the value of simulation because of its flexibility and efficiency. Years ago, at Hughes, we built the phased-array antenna for the B2 bomber. The feed on that antenna had cross-guide couplers with crossed dog-bone-shaped slots coupling from one to the other waveguide. In the lab, we had a custom-machined test fixture with roughly 100 unique slot inserts of varying slot length so that we could measure coupling and return loss as a function of slot length. Days and days of measurements were performed to build up a design Christian Louboutin Shoes sale for that coupler. Today, I can run a parametric simulation in HFSS to fully characterize that coupler in just a few minutes! What's more, I can connect that coupler with models for the rest of the feed in a circuit simulation and optimize power distribution, phase, and bandwidth while including all 3D EM effects. Many of our customers trust simulations so strongly that they now avoid prototyping such a system.Measurements are essential for characterizing materials and/or validating results of larger systems that may Christian Louboutin Pumps the capacity or scope of simulation.
