Recently, I got a request to help with some questions regarding the use of JMLC inspired Horn calculator. Usually, I have not much spare time to help in detail, but this time was indeed different because there was a well balance of give and take.

Adam contacted me with a very nice performance JMLC horn using PETF to optimize the profile with respect to better directivity control while greatly preserving loading. It is not as good as my WN300, but I was surprised about the results. With some minor suggestions from my side to further optimize PETF parameters, Adam worked almost without my help using his own workflow. It has been proven that my splines export function is working perfectly to create a step file and then mesh the BEM components using GmsH.

Overall, we settled down quite fast with a really outstanding results for a JMLC horn and all this was only possible using the PETF algorithm because the native JMLC profile tends to beam.

It has been shown that Adam not only has excellent knowledge of BEM simulations, but also exceptional technical skills and his own equipment. I can only express my deep respect for this result, and will now simply let the pictures do the talking:
