Abstract: It is shown that periodic knife-type gratings always have waveguiding and anomalous properties. The dispersion relations for waveguide modes are obtained and the passbands are determined. The asymptotical form of the dispersion relations is obtained with an infinite increase in the length of the cascade elements and a decrease in the wave number. The effect of the geometrical characteristics and the type of grating on its waveguiding and anomalous properties is investigated.
