The derivative equations are precisely the electrostatic and magnetic equations for empty space with cylindrical symmetry. The solution is thus that of an infinite line charge and an infinite straight current:
|

\[
|
||||
{\boldsymbol E}_0 (s, \phi) = \frac{A}{s} \hat{\boldsymbol s}, \hspace{10mm}
|
||||
{\boldsymbol B}_0 (s, \phi) = \frac{A}{cs} \hat{\boldsymbol \phi}
|

{\boldsymbol E}_0 (s, \varphi) = \frac{A}{s} \hat{\boldsymbol s}, \hspace{10mm}
|

{\boldsymbol B}_0 (s, \varphi) = \frac{A}{cs} \hat{\boldsymbol \varphi}

\]

where \(A\) is a constant amplitude. Substituting and taking the real part,

\[
|

{\boldsymbol E} (s, \phi, z, t) = \frac{A}{s} \cos (kz - \omega t) \hat{\boldsymbol s}, \hspace{10mm}
