WebNote: Total power of this 2D source is only a fraction of the pre-defined beam power. E1-field orientation-2D: If 2D source width checkbox is enabled, E1 field orientation can be specified. 90 degree means the E1-field is perpendicular to the length of the 2D source while 0 degrees means the E1-field is parallel to the length of the 2D source ... WebQuestion: Problem 4: (15 marks) Here we consider a Gaussian beam. We define the total power P(z) carried by a Gaussian beam at position z along the direction of propagation by the integral of the intensity I over a transverse plane, i.e. P(z) = SS dAI (p, z), transverse plane where dA denotes an infinitesimal surface element.
