This paper deals with the simulation study using COMSOL on the deformation of drop-within-drop system in a high intensity oscillating electric field. It consists of a composite drop suspended in a continuous phase. This composite drop has a smaller inner drop suspended within the larger outer drop. The outer drop is made up of another immiscible liquid. A high intensity sinusoidally varying axial field is imposed on the system. In this paper, we have studied deformation of the individual drops and compared the deformation of the outer drop in the presence/ absence of the inner drop. The viscous effect slows down the response of the outer drop and hence it cannot regain its original spherical shape during the quarter cycle period of ebbing-field. Hence, with each cycle, the drop deformation continues to increase till steady state is reached. Although, the outer drop shows the same steady deformation in the presence and in the absence of the inner drop, the presence of the inner drop slows down the response of the outer drop.
