Typically photon attenuation is determined by the equation [itex]I = I_0 \cdot e^{ - (\mu \cdot z)}[/itex]. The variable mu is the linear attenuation coefficient and z is the distance traveled through the substance of transport. Is it safe to say that [itex]I_0 \cdot e^{ - (\mu \cdot z)}[/itex] is the damping term of the electromagnetic wave for the photon? My question is can I write [itex]I(z,t) = I_0 \cdot e^{ - (\mu \cdot z)} \cdot e^{i \cdot (k \cdot z - \omega \cdot t)}[/itex].(adsbygoogle = window.adsbygoogle || []).push({});
