Propagation constant a conductor. The skin effect causes R along the conductor to be approximately dependent on frequency according to Losses in the dielectric depend on the loss tangent (tan "δ") of the material divided by the wavelength of the signal. Thus they are directly proportional to the frequency. The attenuation constant for a particular propagation mode in an optical fiber is the real part of the axial propagation constant. In electromagnetic theory, the phase constant, also called phase change constant, parameter or coefficient is the imaginary component of the propagation constant for a plane wave. It represents the change in phase
The Wave 96.4 FM The Wave 96.4 FM 96.4 The Wave is a British Independent Local Radio station that serves the Swansea Bay area of West Wales. The station is owned by Wireless Group and mainly broadcasts chart and contemporary music, alongside news and local information, for an audience of under 40s. Initially broadcasting as 95.1 Swansea Sound on 30 September 1974, the station split into two separate services on 30 September 1995, creating a new music-led station called 96.4 Sound Wave when it moved its frequency from 95.1 FM to 96.4 FM, while Swansea Sound continued to broadcast on 1170 AM.
