Hello, my friend:(adsbygoogle = window.adsbygoogle || []).push({});

Recently, I encounter a matlab program problem on the propagation of the soliton in

dielectric . I find that many people use a beam propagation method ( split-step fft ) in order

to simulate this procedure. But I cann't get incorrect result.

I am eager to get help from my friend who am good at this method . Thank you!
