    Chapter 1:Vector and Field

    In vector calculus, a vector field is an assignment of a vector to each point in a subset of Euclidean space.[1] A vector field in the plane, for instance, can be visualized as a collection of arrows with a given magnitude and direction each attached to a point in the plane. Vector fields are often used to model, for example, the speed and direction of a moving fluid throughout space, or the strength and direction of some force, such as the...

    Electromagnetic Fields

    Electric fields are created by differences in voltage: the higher the voltage, the stronger will be the resultant field. Magnetic fields are created when electric current flows: the greater the current, the stronger the magnetic field. An electric field will exist even when there is no current flowing. If current does flow, the strength of the magnetic field will vary with power consumption but the electric field strength will be constant.

    Chapter 2:Michael Faraday.

    An electric field is the region of space surrounding electrically charged particles and time-varying magnetic fields. The electric field depicts the force exerted on other electrically charged objects by the electrically charged particle the field is surrounding. The concept of an electric field was introduced by Michael Faraday.

    Chapter 3: Magnetostatic Fields

    Magnetostatics is the study of magnetic fields in systems where the currents are steady (not changing with time). It is the magnetic analogue of electrostatics, where the charges are stationary. The magnetization need not be static; the equations of magnetostatics can be used to predict fast magnetic switching events that occur on time scales of nanoseconds or less.[1] Magnetostatics is even a good approximation when the currents are not...

    Chapter 5: Theory and Applications of Transmission Lines

    Presents the latest methods for properly considering transmission line effects as well as the calculation of transmission line properties as a function of materials and geometries. Emphasizes properties of stripline and microstrip circuits, explaining that at high enough frequencies, almost every interconnection in a circuit will exhibit transmission line properties. . , that, if these circuits are to be well designed, the transmission lines...
