Dear Prof. Johnson and Meep community members,
I apologize if this message appears similar on the post in the
MPB-discuss newsgroup. I have a question about how to use Meep to solve
a problem on curved waveguides (circular ring).
My goal is to obtain the effective index and mode profile of the
quasi-TE and quasi-TM modes in a curved waveguide in 3D.
I have read the holey waveguide tutorial where the w(k) relation was
obtained once a cell unit is defined and the direction of periodicity of
the Bloch wavevector k is also defined. My problem is how do I define
the periodicity of a 3D circular ring waveguide.
One approach I was thinking of is that perhaps the wavevector should
have two components in the x and y directions following a circular path.
Please correct me if that is not the case.
I appreciate any comments or alternative approaches you may know about.
Thanks for your time.
Regards,
