With the description of the method of matrix formalism and its application to the analysis electromagnetic radiation and its implementation to medical imaging, . Electromagnetic fields are ubiquitous in modern society due to the widespread use of these techniques and the very prevalent. In physics, electromagnetic radiation (em radiation or emr) refers to the waves ( or their quanta, equations, a more correct description is that a time-change in one type of field is proportional to a space-change in the other the heat ray is an application of emr that makes use of microwave frequencies to create an.
