章節大綱

L28A
        Lesson 7: Time-Varying fields 2
        Why time-harmonics? 
        Scalar to vector phasor notation 
        Frequency-domain Maxwell’s equation 
        Wave vector, wavelength, frequency 
        Phasor-domain: compared to lossless T-Lines 
        Waves in lossy medium: complex permittivity 
        Complex permittivity > complex wave number
 
 
 
L28B
        Lesson 7: Time-Varying fields 2 
        Example: moist ground and gold  
        The EM spectrum 
        Polarized and unpolarized media 
        Induced polarization in dielectric media 
        Inhomogeneous wave equation 
        Source of EM Waves
 
 
 
 
L28C
        Lesson 7: Time-Varying fields 2 
        Time-varying e-dipole 
        Light propagation in medium 
 

 
L28D
        Lesson 7: Time-Varying fields 2 
        Place waves 
        Solution to scalar Helmholtz’s equation 
        What about M-field?
