A. Electromagnetic Waves. Definition. While it sounds somewhat psychedelic, an electromagnetic wave (EMW) is, in the workings of physics, defined as a wave produced by the interaction of time-alternating electric and magnetic fields. Both electricity (your hair sticking straight up) and magnetism (a refrigerator magnet) can be static The standard description of wave polarization in the trans- verse plane of propagation of an electromagnetic wave is given by the Stokes parameters @1#. As is well known, these parameters can be found from the two-dimensional coher- ency tensor, constructed from the transverse components of the wave field Hence such wave is called as elliptically polarized. Propagation of EM Waves in Different Mediums. In electromagnetic fields, the materials are classified as conductors, dielectrics and lossy dielectric. The electrical parameters such as µ, є and σ are the variable parameters that decide the type of medium The intensity of the EM wave before and during the passage of the gravitational wave is given by the parameters \(s_0\) and \(S_0\), respectively. From the definition of \(\Omega \) , it follows tha Electromagnetic waves are effected by the medium they are propagating in. Even in the vacuum of space, they are affected by gravity (look up gravity lens). There are two paramaters that are most fundamental. The permittivity of a medium describes.
