he gap discontinuity of the dielectric strip in the GNRD is analyzed transversely and longitudinally by employing the field-matching method. At first,the dispersion characteristics of the propagating mode and the evanescent mode are discussed, then the curves of reflectivity with respect to the gap are given. Finally, the theoretical and experimental data are compared, and they are in agreement with each other.
