    Fresnel Equations for a beam instead of a plane wave

    sgd37, First of all, thank you for your interest in the topic and your previous replies. The question, as I mentioned above, is taken from Problem 6.2-3 in Fundamentals of Photonics, 2nd Edition, by Saleh and Teich (and no further information is provided). My undestanding is that the book...

    Fresnel Equations for a beam instead of a plane wave

    sgd37, You can go for a rigorous treatment of the topic (please check this reference: http://webee.technion.ac.il/courses/046244/files/ComplexPointSource.pdf), which as you can see is not straighforward, but in this case I need just a few sentences explaining how to tackle the problem...

    Fresnel Equations for a beam instead of a plane wave

    Could a spatial Fourier transform be used? I'd really appreciate if anyone could share his/her thoughts and perhaps provide more elaboration

    Fresnel Equations for a beam instead of a plane wave

    Note: The question is related to Problem 6.2-3 in the Fundamentals of Photonics book, by Saleh and Teich.

    Fresnel Equations for a beam instead of a plane wave

    In many books we can find the derivation of Fresnel Equations (TE and the TM reflection and transmission coefficients), but always for the case of a plane wave. How can we go about obtaining the reflection coefficient if the incident light took the form of a beam rather than a plane wave? We...
