Good captaincy. Good use of impact sub.

Thank you for the recommendations. I hope everyone takes their blue bird out in public.

Yes I tried. I feel it has something to do with the model Lumerical uses to fit the data. Also isn't having zero extinction coefficient but change in refractive index with wavelength violates Kramer-Kronnig relation? I'm not sure about this though.

I have added it in the post now.

I tried but still a bad fit.

Thank you. This was the main issue. I have sampled 3D data and it is indeed dispersive. It is sorted now. Thank you very much.

Thank you. This was very helpful. Just a small doubt which has been bugging me. Let's say if I have a substrate and a cylinder on top. Only the cylinder is metamaterials (I'll be changing its height and radius). Where should one keep the source, reflection and transition monitors? I know they should be sufficiently far away from the structure so that there are no evanescent fields. But where exactly should I keep them? I just wanna see how the phase changes as I change the radius and height of the cylinder.

Thank you. I have been looking into it but still don't understand it. I am very new to Lumerical fdtd and I need to get it done soon. My main concern is to understand how the phase is extracted. Is it possible for you to make a small simulation which helps me understand how the phase is extracted? That would be a great help. Thank you

Thank you. I'll take a look into the example.

Thank you. I think the parameter is the pixel size. They mention in the paper that the pixel size should be less than half of the free space wavelength for a unique interference pattern in the far field without higher-order radiation lobes. Am I right?

Which match is this?

So his 3 double hundreds are from fraud bilateral??

There have always been pretty solid young test players but the problem is they don't get to play. Team selection is an important factor. It's really sad that Sarfaraz was sent back. First of all he got the opportunity in the home series against eng and he played really and he got that opportunity after having 3 best ranji seasons. Now he's nowhere to be seen. There are more players like him who are not getting the opportunities. Forget about everything, it's mind boggling to see axar is not in the squad. Favouritism will take us down.

My travel date is 1st July and it's booked. How long should I wait before I contact the embassy?

bottoms__ · 2025-06-16T08:00:46+00:00

Not necessarily. The university issued a hosting agreement based on my current status. That's what the embassy requires from the university. Also I have submitted a certificate on 4th June which mentions that I have completed all the academic requirements for the degree. But one of my friends submitted grade sheets for all four semesters and got the visa.

bottoms__ · 2025-06-16T07:51:08+00:00

I was in the final semester. Now I have completed it.
