A waveguide is a structure which guides waves, such as electromagnetic waves or sound waves. There are different types of waveguides for each type of wave. The original and most common[1] meaning is a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves.

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...

EM-Ch4_1 3 a) Introduction to Time Varying Fields Electric charges induce electric fields and electric current iduce magnetic fields. the cases for magnetostatic and electrostatic where the magnetic field and the electric field are constant with time. In the magnetostatic and electrostatic cases, the E and D fields are independent of B and H fields.

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...

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.

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.
