Matrix fill in analysis of axially symmetric antennas using very high expansion orders

The new implementation of max-ortho bases in a method for analysis of axially symmetric antennas is examined from the aspect of analysis-time requirements and average number of integration points per system matrix element. Results for a thick dipole antenna show that for the same number of unknowns, expansion orders up to 64 require fewer resources than lower order bases (i.e. 1
^st
and 2
^nd
order).
