Gk. Gothard et al., FINITE-ELEMENT SOLUTION OF OPEN REGION ELECTROSTATIC PROBLEMS INCORPORATING THE MEASURED EQUATION OF INVARIANCE, IEEE microwave and guided wave letters, 5(8), 1995, pp. 252-254
In this work, we utilize the finite element technique to open region p
roblems in conjunction with the truncation condition based on the meas
ured equation of invariance (MEI) concept. The major advantage of the
present scheme is a significant reduction in the number of unknowns wh
ile retaining the sparsity of the generating matrix. Typical numerical
results are presented for the solution of Laplace's equation to illus
trate the accuracy of the technique.
