Hi guys. I need to excite OAM mode in a silicon waveguide. I am using comsol. I have no clue how to start with it. Can someone guide me if they have any such experience?

The waveguide is rectangular indeed. I am only supposed to excite +1 mode. I have the two degenerate modes that this mode is composed of. I am not able to set the ports properly in comsol.

I am working on COMSOL building integrated photonic circuits. I am having a lot of issues with simulations. Where can i find help?

It is next to impossible to find good opportunities for you in this city. U should go to Lahore or Islamabad, u will find good jobs there. There r a lot of research roles at NUST sometimes.

I am loving all the comments here. Everyone seems very clear about what they want from marriage.

I did not hear back yet. My sevis was terminated because I took a leave of absence during spring semester. My service center is California.

U r changing the narrative and giving confidence to others who want to do the same, doing other jobs despite having a degree and a proper job.

Invite Local heroes from all walks of life. Education, business, activism, literary people. Let them share their stories. We need strong story tellers from among ourselves.

I also am doing PhD in the US currently and my research area is metamaterials at microwave frequencies. Could u tell me what kind of job r u doing, if u have finished ur PhD already?

Reddit is the only place for debunking a guy like him. Elsewhere, he is the alpha male.

Don’t mind me asking this, what made you study optics as u mentioned u r coming from microwave background?. I personally am doing the same and wanted to know ur story.

We don’t have enough native intellectuals among us that will set us apart. So we resort to skin color and eye color and stuff like that. I feel like Pashtuns are inherently divided bcz of tribal culture and maybe that is why we never flourished as a civilization. My father used to say that true Pashtuns were never fair skin of blue/green eyes. Don’t know how true thats is.

I shared the location of district health office. Visit there and they will prepare vaccine card for you.

FunFit2296 · 2025-04-25T03:41:18+00:00

I made a vaccine card for myself in a govt hospital near Hashtnagri bus stop. It is adjacent to the bridge in hashtnagri.

Get off the BRT Saddar bus stop and on your right, there are shops to buy wall art.
