摘要:
The immense potentialities of communication satellites open a wide field of vision for communication engineers. Communication satellites so far launched have established their usefulness for intercontinental circuits. Performance of such types of satellites—already launched—has been reviewed in brief. The problems facing the engineers in establishing a commercial set-up for communication through satellites have been discussed. A probe has been made in the future when a communication satellite will be able to provide global coverage for voice and television signals in the most convenient manner.

摘要:
Mueller has developed an atomistic theory of photoelasticity for transparent, isotropic solids like glasses wherein the validity of Lorentz-Lorenz law is varifled. An extension of this theory and an empirical assumption that the fractional change in polarizability of an ion within the glass is proportional to the applied stress has allowed the present author to make a theoretical expression for the photo-elastic constants. This expression contains some atomic parameters which relate the change in polarizability to the applied stress. It is shown how these parameters can be calculated from an accurate experimental determination of the photo-elastic constants.
