Hello,

currently i have to make a spiral wave with an impressed current in FEKO 2018.

For the generation of spiral wave we can use a normal plane wave.

The amplitude of this plane wave shall not be only 1 but also 1*exp(j*m*phi), where m is a constant like 1 and phi is the phase from 0 till 360.

How can i make?

 

please check this picture.

Thanks in advance

 

Best Regards

Mohamed

    Hi Kuzi


    Would these options under the plane wave source help?
