The estimation of the reactance of a loss-free surface supporting surface waves

The transmission-line analogue technique has been applied to calculate the reactances of a few types of surface which may support surface waves. Experimental methods of estimating the reactances of such surfaces have been discussed, with special reference to the difficulties encountered in practice. Results obtained by theoretical calculations have been found to agree with experimental results within the limits of experimental error and the validity of the assumptions made in the theoretical calculations.
