Dear All, I am unable to understand a simple mathematics relation. I spent 2-3 hours to Google multi-variable mathematics and have studied some concepts, still i am missing/confusing some basics. The problem I have at hand is following. Vector p can be written as p = (p1, p2, p3) = n(sin θ3...

Dear All, I need you kind support in a problem, which I am unable to figure out. It is regarding thick lens. I am determining lens principal planes and radius using shaping factor and focal length. The forward problem I am using is, Focal length 1/f = (n-1)*[1/r1 - 1/r2...

Many Thanks for your elaborate response. It cleared me the concept.

Dear All, I am confusing total internal reflection for a light wave traveling from denser medium to lower dense medium. I know we get lateral shift i.e. goos hänchen shift with total internal reflection, but Do we have phase shift due to goos hänchen shift with total internal reflection...

Many thanks for your humble reply. I used the Normalization constant calculated for step index fiber LP11 mode (shown in figure) but the values are in range of 10^6 and later i use them for measuring smthng and get erronous results...Kindly inform me are there any formulas for LP01 and LP11...

Dear All, Many thanks for reading this query. Actually, I am having problem in measuring the mode fields of Optical fiber at the core-cladding interface analytically for modes LP01 and LP11. The modes are normally given by eq 2.165 (image attached). To my knowledge these constants A and C...

Many Thanks For the reply it cleared a lot of concepts...

Dear All, I appreciate the efforts and support of members/admin here toward the goodness of education. I am confusing a few concepts regarding diffraction, kindly help me out. I came up with following questions, 1. Is apperture required for diffraction or any finite wave will diffract...

Many Thanks For your humble reply. I understood the normal modes in physical medium and i am curious how they relate to normal modes of light propagation in anisotropic crystals. The normal modes travel along principle axes for anisotropic case. Why along the principle axis?? and i am not sure...

Dear Friends, I am new to this forum and I am not sure whether I am writing my Query in the correct section or not...If not Kindly guide me where to post this... I am confused about what are normal modes of propagation in isotropic or anisotropic media?? or How one can define Normal modes...
