MagnetostaticsWe saw in Sect. . that Maxwell equations decouple into two sets; one set belonging to electrostatics, and the other belonging to magnetostatics. We treated electrostatics in Chap. .. In this chapter, we study magnetostatics.

Waveguides and CavitiesTransmission lines can be used to transmit waves effectively below the microwave regime. In the microwave regime and beyond, they become less efficient due to high attenuation.

Electromagnetic Radiation and Auxiliary PotentialsIn this chapter, we discuss solution of Maxwell equations in the presence of sources, a problem known as a radiation problem.

Antenna ArraysEnhancing the antenna directivity can be done, for instance, by increasing its electrical length. However, this leads to increasing the dissipation, and thus, decreasing the radiation efficiency.

Maxwell Equations and the Structure of Electromagneticsuations in Sect. ., we treat these equations as a set of governing equations relating inputs to outputs. Then, the main target becomes finding these outputs in relation to their inputs. Finally, we see in Sect. . that electrostatics and magnetostatics arise as approximations to the general theory.

Plane-Wave Reflection and Refraction object in the shape of a flat infinite-extent surface (as shown in Fig. .). The entire space is then divided into two regions; a region with medium 1, and a region with medium 2. The surface separating the two regions is called an interface. In this case, part of the incident wave gets reflected by the object, and part of it gets transmitted.
