An explicit formula for the propagation constant of an electromagnetic wave propagating along a very thin conducting wire immersed in a magnetoplasma is obtained for the general case where the static magnetic field is applied with an arbitrary inclination with respect to the wire. An experimental ...
radio waveswave propagationResults 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 ...
However, an electron under acceleration also emits electromagnetic waves, 2 2 e q and its radiation power is given by W ;, where a is the acceleration of the electron. 6炊%Given the radius of the circular orbit R, find the radiation power W, and compare that with the kinetic energy E...

The electromagnetic characteristics associated with the creeping waves supported by a dielectric coated cylinder are investigated. The propagation constants and wave impedances of the creeping waves are obtained numerically. Higher order modes which are significant for a thick coating are also investigated....

Moreover, the commonly employed IR spectroscopy predominantly provides qualitative spectra in terms of absorbance, thereby demanding application of calibration procedures for a quantitative comparison of data across different measurements. (In what follows, the term “calibration” refers to the calculation ...
