Abstract
Double negative materials' phenomena will be discussed and analyzed in this thesis, including slab waveguide modes and
reverse doppler effect of left-handed materials.
When the waveguide is made of left-handed materials, we need to find the differeces between it and conventional waveguides.By using dispersion relations, we can get TM and TE modes, and then their corresponding fields. Surface modes will be also discussed.
Finally, we model the reverse Doppler effect of double negative refractive index materials and double positive refractive index materials.Interestingly we find when an object is moving away, the former will lead to blue-shift while the latter will lead to red-shift.
