Weber,General Relativity and Gravitational Waves (Interscience, New York, 1961). The solution due to J. Weber of the coupled Maxwell Einstein equations for an antenna with electromagnetic instrumentation is given on pp. 263–279 ofProceedings of the International School of Physics, Enrico Fermi Course LVI, B. Bertotti, ed. (Academic Press, New York, 1974).
