Abstract : The scattering matrix of a 360 circumferential slot in an infinitely long circular wave guide (with an incident dominant circular-electric wave) is obtained by a variational principle. The characteristics of a gap of this type in 5.755-in.-id brass tubing were measured at a free-space wave length of 10,000 cm. The experimental values of amplitude and phase as determined separately by Deschamps' method were in excellent agreement with the theory for values of 2 g (gap width) up to 1.000 in., corresponding to g/lambda = 0.127. The validity of the theory was only claimed for values of (g/lambda) 2 1.
