Hi, Does complex refraction angle have any limitation on its real or imaginary part? Does one of these part have to be positive or negative only? Thanks, Elad

tech99 - what do you mean by theta and why cos? pines-demon - I got the form n^2*sigma*T^4 from the book thermal radiation heat transfer (Howell and Siegel). According to the book: "If the refractive index is constant with frequency, integrating equation 17.44 over all ni yields the local total...

Hi. If the refractive index of a medium equals one, the total emitted blackbody intensity inside a medium is sigma*T^4. In general, if the refractive index of a is a real number, the total emitted blackbody intensity inside a medium is n^2*sigma*T^4. Now, when the refractive index of the medium...

Hi, Refractive index can be complex. When Snell's law is taken into account refraction angle can also be complex. What is the meaning of the imaginary part and the real part of the refraction angle? Which angle should I take into account when I want to follow the direction of a thermal...
