Sub-wavelength metallic waveguides loaded by uniaxial resonant scatterers [PDF]
MELECON 2006 - 2006 IEEE Mediterranean Electrotechnical Conference, 2005 The dispersion properties of rectangular metallic waveguides periodically loaded by uniaxial resonant scatterers are studied with help of an analytical theory based on the local field approach, the dipole approximation and the method of images.
