EE 3320 Lecture : Notes 2
Document Summary
We will be interested in studying the behavior and relationships between four dynamic electromagnetic vector field quantities: The source of the static electric field is the charge density, volume charge density. The subscript v denotes that this is a. Additionally, a time-varying electric field arises in the case of a time-varying magnetic field. r. The source of the static magnetic field is the steady state current density, j. Additionally, a time-varying magnetic field will arise in the case of a time-varying electric field. These fields are related to each other via constitutive parameters that are functions of the material environment through which the electromagnetic field is passing and in general are not constants. How these parameters relate to the fields are together known as the constitutive relations: (definition of permittivity, . S ) m refers to the conduction current density about which we will have more to r.
