Overview of Applied Electromagnetics
Applied electromagnetics is a branch of engineering that deals with the application of electromagnetic theory to solve practical problems in various fields.
It encompasses a wide range of topics, including the study of electric and magnetic fields, electromagnetic waves, transmission lines, waveguides, antennas, and microwave circuits.
Applications of Applied Electromagnetics
- Wireless communication systems
- Medical imaging
- Radar and remote sensing
- Power generation and distribution
- Electric motors and generators
- Sensors and actuators
Electromagnetic Fields and Waves
Electric and magnetic fields are two fundamental concepts in electromagnetics.
Electric fields are created by electric charges, while magnetic fields are created by moving electric charges.
Properties of Electromagnetic Waves
- Electromagnetic waves are transverse waves, meaning that their electric and magnetic fields are perpendicular to each other and to the direction of propagation.
- Electromagnetic waves travel at the speed of light in a vacuum.
- The wavelength of an electromagnetic wave is inversely proportional to its frequency.
Transmission Lines and Waveguides: Fundamentals Of Applied Electromagnetics 8th Edition Pdf
Transmission lines and waveguides are used to guide electromagnetic waves from one point to another.
Transmission lines are typically used for low-frequency applications, while waveguides are used for high-frequency applications.
Characteristics of Transmission Lines
- Transmission lines have a characteristic impedance, which is the ratio of the voltage to the current on the line.
- The characteristic impedance of a transmission line is determined by the geometry of the line.
- Transmission lines can be used to match the impedance of a source to the impedance of a load.
Antennas and Propagation
Antennas are used to transmit and receive electromagnetic waves.
The design of an antenna depends on the frequency of the electromagnetic waves that it is intended to transmit or receive.
Principles of Electromagnetic Wave Propagation, Fundamentals of applied electromagnetics 8th edition pdf
- Electromagnetic waves propagate through space in straight lines.
- The speed of electromagnetic waves in a medium is determined by the permittivity and permeability of the medium.
- Electromagnetic waves can be reflected, refracted, or diffracted when they encounter an obstacle.
