19 | | In all of these cases Lemma is in excellent agreement with Leroi, the main differences can be seen in fairly low-order effects near the loop corners. This difference can be attributed to the fact that Lemma integrates around a current source, using horizontal electric dipoles (HED). Leroi and most other codes decompose the surface area of the loop and approximate the surface with vertical magnetic dipoles (VMD)~~ ~~. The VMD approach will therefore smooth out sharp corners. However, in reality, wires do not make perfectly sharp corners, and either approach is valid. |
