Reply To: How to find out Phase shift of transmitted wave varying radius vs wavelength

[Afroditi Petropoulou]

Dear Nayem,

What you plot is the phase. The paper plots the phase shift. As you can see, the calculated phase has a range between -3.14 and 3.14, while the phase shift plotted in the paper has a range between 0 and 2. Is there a refernce phase discussed in the papaer? What does a phase shift means in the paper you mention?

If there is a reference phase then you need to subtract it from the one you caclulated. 

Best Regards,
