Left-Handed Materials (LHMs) in contrast to conventional materials, exhibit an anti-parallel nature in the electromagnetic wave propagation and Poynting vectors. Exciting possible electrodynamic properties for LHMs, such as reverse Doppler shift, Cherenkov radiation and inverse Snell effect, were identified. However, the construction and application of LHMs has yet to come to fruition. Recently, we demonstrated that negative refraction phenomenon presented by LHMs can be found in generalized Electromagnetic Crystal Structures by application of Floquet's Theorem and spatial harmonics theory. In this proposal, the concept will be further studied with the aim to design and construct LHMs from planar structures currently employed in Electromagnetic BandGap applications.Overall, the proposed research aims to develop novel modelling tools and new types of antenna based on LHMs for future industrial exploitation. Novel numerical algorithms will be developed to combine the dispersive and conformal FDTD algorithm together with new absorbing boundary conditions for LHMs. Sample antennas based on LHMs will be fabricated and measured to validate the models and demonstrate the benefits of using LHMs. Such antennas will be expected to be low profile and exhibit high gain that was only previously achievable with conventional substrates by using large arrays, lenses or reflectors. We also plan to investigate applications for the frequency selective nature of LHM refraction. Such applications include a narrow band receive radom to reduce antenna RCS and compact dual beam feeds for SATCOM antennas.
