Physics is part of any curriculum in science and engineering. The main objective of this course is to help students of engineering and other sciences in more advanced courses in these fields. The textbook will introduce the students to the fundamental concepts of physics and how different theories developed from physical observations and phenomena. It starts with electrostatics in free space, introducing basic concepts, such as Coulomb's electric charge law and ideas of electric field and electric field lines (Chapter 1). Chapter 2 introduces the electric flux and Gauss's law. Electrostatic potential and electrostatic potential energy are introduced in Chapter 3. Chapter 4 presents the concepts of capacitance and dielectrics. Also, the electrostatics of a macroscopic medium and Maxwell's equations of the electrostatic field are discussed.
Chapter 5 introduces the concepts of electric current and Ohm's law. Chapter 6 continues with the magnetic field and its interactions with charges and currents. Then, Chapter 7 introduces the concept of magnetic field sources, where Biot-Savart law and Ampère's law are introduced. Chapter 8 describes magnetism in the medium, Faraday's law, and Maxwell's magnetic field equations. Then, Chapter 9 describes Maxwell's equations of electromagnetic fields. In particular, this chapter focuses on the potential vector and scalar of the electromagnetic field, electromagnetic field energy, and conservation laws. Then, the dynamics of charged particles in the electromagnetic field and averaging of microscopic properties to obtain the macroscopic Maxwell's equations are introduced. Chapter 10 describes some advancing topics on the induction law and alternating current circuit systems, aiming at understanding electromagnetism applications to wireless charging.
Chapter 11 introduces some applications of the theory of electromagnetism in macromolecular solutions and wireless charging technology. Chapter 12 introduces electromagnetic waves in vacuum and medium, coherence of electromagnetic waves, the polarization of electromagnetic waves, reflection and refraction of electromagnetic waves, and Fresnel's equations. Chapter 13 introduces electromagnetic wave equations in dispersive media. This chapter also describes the absorption, Lorentz's oscillator model of a dielectric, the wave equation of a conductor, the wave equation of a dilute plasma, and the magnetized plasma or dielectric. Besides, Appendix introduces some mathematical background in vector analysis and vector differential operators. The textbook is geared more towards examples and problem-solving techniques. The students will get a firsthand experience of how the theories in physics are applied to problems in engineering and science. The textbook is mainly aimed at undergraduate students in engineering and science.
However, some chapters and sections are aimed at senior undergraduate students working in the final year thesis in theoretical and computational biophysics, physics, electrical and electronic engineering, and chemistry.
