You should change absorption coefficient and wavelength in to MKS unit
Sir I think while converting the values for k it is mistake so the graph looks different for dielectric constant
It is very useful video. Thank you. I'm a bit confused - from simulation data we see that the value of real and imaginary part of dielectric function are not so much different than you showed us. Is it reliable?
KIndly give te link of this paper so that we can cite it.
Thank you for this video, is this reflectance DRS or absorbance?
Hello, can you please provide the title of the paper? Don't you think your alpha and lambda should have the same units when calculating k? That would make k unitless in this case.
Which method your using to calculate n, dielectric constant
Can you explain why imaginary part is positive while real part is negative??
I think you forgot to put 4 pi in parentheses the way you entered k formulae is wrong and thus your k is wrong.
Then the published article will be also wrong.. Because, I taken that expression one of the article📰
@@NanoencryptionSKP kindly cite the article for reference
@@NanoencryptionSKP So how can I extract the n number FROM THE TWO CURVES ???
Even calculation for "n" was wrong .... should have taken squareroot inside parenthesis like ^(1/2)
You forgot unit conversion! Fix your units before plotting the real and imaginary epsilons. If this work is published as is, then the reviewers were not paying attention.
