TAILIEUCHUNG - Electromagnetic Field Theory: A Problem Solving Approach Part 3

Electromagnetic Field Theory: A Problem Solving Approach Part 3. Electromagnetic field theory is often the least popular course in the electrical engineering curriculum. Heavy reliance on vector and integral calculus can obscure physical phenomena so that the student becomes bogged down in the mathematics and loses sight of the applications. This book instills problem solving confidence by teaching through the use of a large number of worked problems. To keep the subject exciting, many of these problems are based on physical processes, devices, and models. This text is an introductory treatment on the junior level for a two-semester electrical engineering. | Contents xvii Doppler Frequency Shifts 507 Ohmic Losses 508 а Low Loss Limit 509 б Large Loss Limit 511 High-Frequency Wave Propagation in Media 511 Dispersive Media 512 Polarization 514 a Linear Polarization 515 b Circular Polarization 515 Wave Propagation in Anisotropic Media 516 a Polarizers 517 b Double Refraction Birefringence 518 NORMAL INCIDENCE ONTO A PER- FECT CONDUCTOR 520 NORMAL INCIDENCE ONTO A DIELECTRIC 522 Lossless Dielectric 522 Time-Average Power Flow 524 Lossy Dielectric 524 a Low Losses 525 b Large Losses 525 UNIFORM AND NONUNIFORM PLANE WAVES 529 Propagation at an Arbitrary Angle 529 The Complex Propagation Constant 530 Nonuniform Plane Waves 532 OBLIQUE INCIDENCE ONTO A PER- FECT CONDUCTOR 534 E Field Parallel to the Interface 534 H Field Parallel to the Interface 536 OBLIQUE INCIDENCE ONTO A DIELECTRIC 538 E Parallel to the Interface 538 Brewster s Angle of No Reflection 540 Critical Angle of Transmission 541 H Field Parallel to the Boundary 542 APPLICATIONS TO OPTICS 544 Reflections from a Mirror 545 Lateral Displacement of a Light Ray 545 Polarization by Reflection 546 Light Propagation in Water 548 a Submerged Source 548 b Fish Below a Boat 548 Totally.
