(a) Simulated resonant modes for an array of 200nm square dots with 100nm interdot separations are plotted as a
function of the azimuthal angle ( ) of the bias field. (b) Powerand phase distributions of the simulated modes are shown for
four di®erent values of . The color scales are shown at the top right corner of the figure.
