Determine the capacitance for the following configuration where the conducting plates are on front (with the permittivity labels) and back faces of the sturcture. Assume $L=5$ cm, $W_1 = 1.3$ cm, $W_2 = 4$ cm, $H = 3$ cm,
$\epsilon_{r1} = 4$ and $\epsilon_{r2} = 5.5$
L
$W_1$
$W_2$
H
$\epsilon_{r1}$
$\epsilon_{r2}$
Answer = pF
