The influence of a spatial periodic variation in the ionosphere's surface impedance is treated theoretically with regard to VLF propagation. It is indicated that substantial mode conversion may take place if the wavelength of the impedance variation is equal to the difference between the guide wavelengths of the two interacting modes.
