ECE Graduate Student Qing He received a Best Student Paper Award at FEM2012 (the 2012 International Workshop on Finite Elements for Microwave Engineering) held at Estes Park, Colorado in June 4-6. Qing’s paper is titled “An Explicit and Unconditionally Stable Time-Domain Finite-Element Method of Linear Complexity.” He is advised by Professor Dan Jiao.

In this paper, an unconditionally stable explicit time-domain finite-element method is successfully created, which is stable and accurate for a time step solely determined by accuracy regardless of how large the time step is. The proposed method retains the strength of an explicit time-domain method in avoiding solving a matrix equation while eliminating its shortcoming in time step. Numerical experiments have demonstrated its superior performance in computational efficiency as well as stability compared with the conditionally stable explicit method and the unconditionally stable implicit method. The essential idea of the proposed method for making an explicit method stable for an arbitrarily large time step irrespective of space step is also applicable to other time domain methods.

Qing received a travel grant of $700 provided by US Army Research Office and an award plaque.
