electromagnetic fields, photonsElectromagnetic modes with parabolic-cylindrical symmetry and their dynamical variables are studied both in the classical and quantum realm. As a result, a new dynamical constant for the electromagnetic field is identified and linked to the symmetry operator which supports ...

2 points Q-6 10 points In classical hydrogen atom model an electron is circling around the nucleus like Earth revolving around the sun, except that the force between the electron and the nucleus is due to the electric field. However, an electron under acceleration also emits electromagnetic ...
If the formula were true, it would be a great aid towards finding a theory unifying the gravitational and the electromagnetic field. It is, therefore, interesting to investigate what conditions the formula would impose upon such a future theory. If we assume that the equations of the new ...
The Electromagnetic Fields and the Phase Constants of Dielectric Image Lines A method is described for the exact calculation of the field distributions and the phase constants of single and coupled dielectric image lines. The theore... K Solbach,I Wolff - International Microwave Symposium Digest...
Electro-optical method and system for in situ measurements of particle size and distribution A system and method provides in situ measurements of the size of particulate matters suspended in fluid medium. A beam of intermittently interrupted electromagnetic radiation is directed through a portion of the...

This speculation was most recently ...
Results of a recent measurement by the author, at a period of minimum solar activity, of the phase velocity and attenuation of electromagnetic waves in the frequency range 40 c/s-10 kc/s are used, in conjunction with waveguide mode theory of propagation for the Earth-ionosphere duct, to ...

Location-dependence of physical parameters such as the electromagnetic fine structure constant and Newton's G produce body accelerations which violate universality of free fall rates testable with laboratory and space experiments. Theoretically related cosmological time variation of these same parameters are ...
