ABSTRACT
The subject of electromagnetic fields is the study of fields created due to moving and/or stationary electric
charges and their applications. The study of electromagnetic fields is important for understanding the basic
principles and design of electrical analog and digital devices and circuits. These digital and analog systems are
expanding the use of GHz range spectrums in communication technology in order to increase bandwidth and
speed. Electromagnetic fields can be divided into three groups (i) steady or static electric fields (ii) static
magnetic fields, and (iii) time varying fields.
