Bro can you tell me the parameter value of operation wavelength in parametric sweep

[@badhogebe4225]

@@tanishqbadyal may be you can download the paper first and look at for the graphs presented for the simulations here

[@badhogebe4225]

@@tasawoufali9980 you mean the wavelength? you can first download the paper and try to retrieve the important parameters for simulation

[@julakantistheya5167]

sir can you please do a video to plot wave length versus refractive index that is given in the paper and also to calculate sensitivity.If possible can you please put .mph file of this simulation

[@mfmawan]

The Txn co. vs RI plot is already reproduced, you just need to sweep the surrounding RI to obtain the sensitivity. just review and follow the instructions given in lecture. Thanks

[@monikakiroriwal6312]

Sir, you have not define Drude-lorentz model for Silver metal, it is not necessary or you have already define it?
