A plane electromagnetic wave travelling in a vacuum is given by E=jE0 exp[i(wt-kz)] (j as vector and w as omega) where E0 is real.

A plane electromagnetic wave travelling in a vacuum is given by  E=jE0 exp[i(wt-kz)] (j as vector and w as omega)where E0 is real. A square loop of side a and resistance R is located in the yz plane with its centre at the origin. Find the current induced in the loop as a function of time, assuming that a is much smaller than the wavelength of the wave.
