Penetration depth is a measure of how deep light or any electromagnetic radiation can penetrate into a material. It is defined as the depth at which the intensity of the radiation inside the material falls to 1/e (about 37%) of its original value at (or more properly, just beneath) the surface. When electromagnetic … Ver mais According to Beer–Lambert law, the intensity of an electromagnetic wave inside a material falls off exponentially from the surface as $${\displaystyle I(z)=I_{0}\,e^{-\alpha z}}$$ If Ver mais The attenuation constant for an electromagnetic wave at normal incidence on a material is also proportional to the imaginary part of the material's refractive index n. Using the … Ver mais • Skin effect • Absorbance • Attenuation coefficient • Transmittance Ver mais WebThe penetration depth is defined as the depth for the 1/e attenuation.
