Solving EDL configuration near a dissimilarly charged protrusions surface model using perturbation method

► Considering both the conditions of dissimilarly charged flat surfaces and of similarly charged protrusions. ► Using Fourier series and perturbation method, EDL configuration of dissimilarly charged protrusions (DCP) surface model is solved semi-analytically. ► Simulating an isolated DCP via the extension of period of charged surface system.
