Query: Low-loss surface modes and lossy hybrid modes in metamaterial waveguides   We show that waveguides with a dielectric core and a lossy metamaterial
cladding (metamaterial-dielectric guides) can support hybrid ordinary-surface
modes previously only known for metal-dielectric waveguides. These hybrid modes
are potentially useful for frequency filtering applications as sharp changes in
field attenuation occur at tailorable frequencies. Our results also show that
the surface modes of a metamaterial-dielectric waveguide with comparable
electric and magnetic losses can be less lossy than the surface modes of an
analogous metal-dielectric waveguide with electric losses alone. Through a
characterization of both slab and cylindrical metamaterial-dielectric guides,
we find that the surface modes of the cylindrical guides show promise as
candidates for all-optical control of low-intensity pulses.
