Complex images for electrostatic field computation in multilayered media

A rapidly convergent algorithm to find the spatial simulated images of a point charge in multilayered media is presented. The simulated images turn out to be complex; i.e. they have complex amplitudes and are located at complex positions. Surprisingly, these complex images give the static field in multilayered media very accurately (errors approximately 0.1%). The examples of two- and three-layered media are examined, together with the available exact image solutions of singly or doubly infinite series.<
