[COMSOL_Users] How to Initiate the gas refractive index value in core of HC-PCF

[s_sivab]

Dear COMSOL Users,

By simulation in COMSOL-RF Module-subdomian settings, how to give the refractive index value of the gas inside the core of Hollow Core Photonic Crystal Fiber.

Many thanks if there is a replay.

With Regards,

Dear friends





I want to apply a periodic biphasic square waveform with the
following properties:

On time: 400us

Frequency: 30Hz

But as I know the only way to build a biphasic waveform is
by using a Waveform, in this case we have symmetric waveform with duty cycle=
50% , and it is not what I need. On the other hand if I use Rectangle function
to set on and off time, the biphasic property of my desired waveform is lost since
this function make a monophasic waveform.

I would be thankful if someone helps me to solve this
problem.


Faithfully yours,
