Abstract
A waveguide dimensioned for fundamental mode operation over a given frequency range is rendered substantially dispersionless by including within the waveguide a thin dielectric slab extending parallel to the E-field of the fundamental mode and having a dielectric constant of at least 4 and a thickness across the E-field ranging between 0.01 and 0.25 guide wavelengths at the center frequency of the given range. Appropriate thicknesses for a dielectric member having a given dielectric constant can be selected to provide overcompensation. The series connection of appropriate lengths of an overcompensated waveguide and uncompensated waveguide yield an overall waveguide having a substantially dispersionless characteristic.
