I do not fully understand your question. Are you saying you produced a thin film and measured the depth of the film (thickness) ? well thats a parameter you use to describe your film for example if it is a film on an electrode it will help to understand the electron transfer/blocking. If it is for corrosion the thickness is crucial etc.

Tomer, I agree with you; I also did not understand Chidambara's question.

Chidambara: A skin depth is (to my understanding) not limited to a film but is applicable to any surface and is related to the type of radiation (electro-magnetic or particles) or the  type of fields (electric or magnetic) passing the surface. The skin depth  depends on the material properties (e.g. its optical constants) and even on the surface properties  such as its roughness. Could you please tell us more details of your calculation and your 'film'. Perhaps we may then have more clarity.

Dear Kumar

I think skin depth is inversely proportional  with absorption coefficient, therefore the values of  absorption coefficient enough to knew your inferences about thin film where can it is useful, and you can easily knew value of skin depth, for example absorption coefficient for thin film equal 10^4 cm^-1, then skin depth will equal 10^-4 cm, this mean penetration depth about 1000 nm, therefore the thickness of absorber layer preferably has a high thickness. Also, there are many parameters relate between one and another. with my best regards
