Cutaway diagram of Coaxial cable, one example of a transmission medium. A transmission medium is a system or substance that can mediate the propagation of signals for the purposes of telecommunication. Signals are typically imposed on a wave of some kind suitable for the chosen medium.
In optics, an optical medium is material through which light and other electromagnetic waves propagate. It is a form of transmission medium . The permittivity and permeability of the medium define how electromagnetic waves propagate in it.
Some of the most common examples of mechanical waves are water waves, sound waves, and seismic waves. Like all waves, mechanical waves transport energy. This energy propagates in the same direction as the wave. A wave requires an initial energy input; once this initial energy is added, the wave travels through the medium until all its energy is ...
The permeability of a medium is related to the porosity, but also to the shapes of the pores in the medium and their level of connectedness. [2] Fluid flows can also be influenced in different lithological settings by brittle deformation of rocks in fault zones; the mechanisms by which this occurs are the subject of fault zone hydrogeology. [3]
A linear medium if the amplitudes of different waves at any particular point in the medium can be added; A uniform medium or homogeneous medium if its physical properties are unchanged at different locations in space; An anisotropic medium if one or more of its physical properties differ in one or more directions
In materials science, a porous medium or a porous material is a material containing pores (voids). [1] The skeletal portion of the material is often called the "matrix" or "frame". The pores are typically filled with a fluid ( liquid or gas ).
Physical medium may refer to: Transmission medium , a system or substance that can mediate the propagation of signals for the purposes of telecommunication Physical mediumship , the manipulation of energies and energy systems by spirits
