WebThese Jν(x) are called cylindrical Bessel functions. The behavior goes from power law to oscillation in the region x ∼ ν. In fact, it's not difficult to find the exact solution as a series. 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 ...
