Abstract :
The effect of slight discontinuities within the measuring arm of a wall-loss bridge is investigated, and it is shown that erroneous values of attenuation coefficient may arise, owing to the presence of such discontinuities. A method is proposed by means of which such errors may be eliminated. Experimental results are presented, demonstrating that significant errors do arise owing to imperfections in the apparatus and that these errors may be removed using the technique described.
