Complex-Potential Analysis of a Slit Model in Electrowetting

Year: 2025

Type: preprint

Abstract: This study develops a complex-potential framework for the electric field near the Triple Contact Point in electrowetting. A global slit model provides the electrostatic potential, surface-charge structure and endpoint expansion. The resulting solution also gives an analytical approximation to the droplet shape and exhibits the characteristic edge singularity of the zero-contact-angle slit model.
