Abstract :
Hexahedral H/sub 0/-curl edge elements provide the means for highly accurate solutions to the Maxwell equations in the high frequency regime. First order hexahedral elements have proven quite accurate for waveguide component modeling, requiring only a modest amount of mesh refinement near conducting corners where field gradients are highest. Second order (H/sub 1/-curl) edge elements have now also been implemented in MSC/EMAS, and testing has shown improved performance in regions of high field gradients.<>
