The Fourier transform of a two-dimensional function

Any periodic function can be written as a Fourier series in the form,

Draw the Fourier transform of the function,

You need to draw the amplitudes cG at the positions of the reciprocal lattice vectors in reciprocal space. The ampitudes may be complex.
