The L(c,p,n) numbers (the common limits of specific infinite sequences of real numbers, defined by the purely imaginary zeros of a special function, being a combination of certain complex Kummer and Tricomi confluent hypergeometric functions) are employed to elaborate an approximate method for computation of the differential phase shift, due to a nonreciprocal digital phase shifter, using a coaxial waveguide with azimuthally magnetized ferrite that supports normal TE0n mode.
