By Ricardo Marqués

The first common textbook to provide an entire assessment of metamaterial idea and its microwave applications

Metamaterials with adverse Parameters represents the one unified remedy of metamaterials on hand in a single handy publication. committed in general to metamaterials that may be characterised by means of a damaging potent permittivity and/or permeability, the e-book incorporates a extensive evaluation of an important subject matters, clinical basics, and technical purposes of metamaterials.

Chapter assurance contains: the electrodynamics of left-handed media, synthesis of bulk metamaterials, synthesis of metamaterials in planar know-how, microwave functions of metamaterial recommendations, and complex and comparable issues, together with SRR- and CSRR-based admittance surfaces, magneto- and electro-inductive waves, and sub-diffraction imaging units. an inventory of difficulties and references is integrated on the finish of every bankruptcy, and a bibliography bargains an entire, up-to-daterepresentation of the present cutting-edge in metamaterials.

Geared towards scholars and pros alike, Metamaterials with adverse Parameters is a perfect textbook for postgraduate classes and in addition serves as a priceless introductory reference for scientists and RF/microwave engineers.

8 WAVES THROUGH LEFT-HANDED SLABS 19 where the two branches, corresponding to symmetric and antisymmetric modes, can be appreciated. The specific dependence of kz on frequency will depend on the specific dependence of 1 and m on v. Surface and volume guided waves in left-handed slabs, also including metallic ground shields, have been analyzed in [37–43]. Finally, it would be worth mentioning that resonant modes in other geometries distinct from planar ones, such as spherical or cylindrical, have been also studied (see, for instance, [44–47], and references therein).

The results are quite similar to those reported in the previous paragraph. 2) for some values of the transverse wavenumber. In such cases, very high values of the transmission coefficient are obtained for the corresponding spatial Fourier harmonic [59], which may distort the image. As left-handed metamaterials are highly dispersive media, this effect may appear for sources emitting radiation pulses of finite duration. The effect of the finite duration of RF pulses in the focusing of rays in the Veselago lens was also analyzed in [61].

This device has been studied and experimentally demonstrated in [79]. 16. TM anticutoff waveguide made with an indefinite uniaxial medium.
