Abstract
Wood's anomalies of resonance type are investigated by means of a rigo rous modal method. Single modal coefficients are used to characterize strength and position of the resonances. With the concept of effective grating periods a formula for the position of resonances with respect to wavelength and angle of incidence is achieved. The influence of va rying grating parameters is discussed.
