Cylindrical wave functions
WebFor a circular waveguide of radius a (Fig. 2.5), we can perform the same sequence of steps in cylindrical coordinates as we did in rectangular coordinates to find the transverse field components in terms of the longitudinal (i.e. Ez, Hz) components. In cylindrical coordinates, the transverse field is ET = ^‰E‰ +`E^ ` HT = ^‰H‰ +`H ... WebTo derive it, consider a plane wave along the x axis, so k ⋅ r = k x = k r cos ( θ), where θ ∈ [ 0, 2 π) is the positive angle from the x axis. Then your plane wave, e i k ⋅ r = e i k r cos ( θ), is a periodic function of θ (for fixed r) and can therefore be expanded as a Fourier …
