Why do magnetic metallic nanowires absorb all the modes of electromagnetic waves when their diameter is less then their skin depth?

How to form a shell around a nanostructure core in solution phase synthesis?

Hey, I want to know if I have fabricated some nanostructure and further I want to make a shell on the nanostructure by solution phase method by making it core-shell nanostructure. So, anybody can...

Metal atoms also absorb radiation!

Rupali Rakshit

As we know, metals are very good reflectors to incident electromagnetic radiation because of their huge conductivity. For this reason, they have very small skin depth, beyond which no EM wave can penetrate. It simply implies that upto the skin depth, EM wave can enter into the metal. Now, if the size of the sample is less than that penetration depth or rather skin depth, then the whole body of individual NW can absorb EM energy.
