A drop freely suspended in another fluid and subjected to an electric field deforms and may either attain a stationary shape or break up. The extent of drop deformation depends on drop-medium physical properties and electric field strength. In a weak electric field, an initially spherical drop assumes a stationary shape close to spheroidal. Inverse optimization facilitates analyzing drop deformation as a function of the physical properties and allows finding cases when the drop may have stationary shapes other than spheroidal, e.g., toroidal shapes and shapes with conical ends.
