Jeffrey (Shih-Hao) Lee is a PhD student in the Center for Computational
Electromagnetics, Univ. of Illinois at Urbana-Champaign.  He is working on
the development and application of the finite element method for analyzing
antennas, high-frequency circuits, high-speed circuits, and so on. The
governing equations are Maxwell's equations.  The matrix results from the
finite-element discretization of a bandpass microwave filter at 500 MHz. The
first-order vector element is employed. The absorbing boundary condition is
applied on the outer boundary of the structure for emulating the open space.
The port boundary condition is applied on each port of the circuit for the
truncating the computational domain and exciting the circuit. Due to these
boundary conditions, the finite-element system matrix is complex.
