Solving these equations we eventually find that if iWQ o, Qt), n, -(j?., o, n, ), + IB cos oS Jx (p) eTMla---5-r. Jo (I + m) (hH + km) The "directed effect" depends on the presence of the terms involving cos oS in the expressions for Qz and Rz. Now when r = oo for the second medium, h = cc, and these terms vanish altogether; hence the possibility of directing the energy of the radiation sent out from the bent antenna is due to the imperfect conductivity of the earth. Von Hoerschlemann has given a numerical discussion of the above formulae but the investigation is too long to be inserted here. 28. Propagation of electromagnetic waves along a straight wire of circular cross-section. Let us consider the symmetrical case when the electric force at any point is in a plane through the axis of the wire H. Hertz, Electric Waves; J. J. Thomson, Proc. London Math. Soc.

The problem considered in this last paper is chiefly that of alternating currents, viz. the forced alternations of flow produced by a uniform periodic electric force. and the magnetic force is ...
