(b) An electric vehicle (EV) using capacitive coupler to transfer power wirelessly as in Figure Q3(b). There are two plates are used for shield plate and four plates as coupler plates in which the dielectric between the plate is air. The plates are fabricated using copper and arranged without additional material. The dimension of the capacitive coupler is stated as in Table 3(b).
