Perturbation theory is applied to one-dimensional scattering systemsconsisting of a general class of inhomogeneous and isotropic slabs having size$L$ described by the relative permittivity $\varepsilon(z) = 1 + \alpha\chi(z)$, where $\chi(z)$ is the electric susceptibility and $\alpha$ theperturbation parameter. The transmitted and reflected amplitudes are shown tobe written as Born series in powers of $\alpha$ and Pad\'e approximants areused to obtain analytical results with a high and arbitrary degree of accuracy.The approach is very general and can handle oblique incidence. Examples aregiven for the transmission and reflection amplitudes of plane waves interactingwith Hermitian and non-Hermitian structures with known and unknown exactsolutions.
