L1_B

        Time-harmonic fields in source-free region

        Why time-harmonics?

        Scalar to vector phasor notation

        Phasor: time → frequency spectrum!

        Frequency-domain Maxwell's equations

        Frequency-domain wave equation

        Wave vector, wavelength, frequency

        Waves in lossy medium: complex permittivity

        Complex permittivity → complex wave number

        The EM spectrum
