According to a study from the United States, "Basis functions play important roles in computational electromagnetics (CEM). It is interesting to investigate the errors in the projection of the equivalent current of a plane wave using various basis functions."
"In this work, the projection error of various basis functions is studied. The basis functions involved are the pulse basis function, the triangular basis function, higher-order versions of these basis functions, and the divergence-conforming basis function on rectangular and triangular elements. The projection errors are derived in closed form. The asymptotic expression of the closed form is given. The ...
