Most flying-wing aircrafts are static and dynamic unstable due to the lack of conventional stabilizers to control the plane in the longitudinal and the lateral directions, and the lateral-directional motion of the static instability flying-wing will cause the coupled longitudinal motion, so the control system is more complicated to design. With this motivation, the longitudinal and lateral-directional...
Propagation of plane waves in an infinite anisotropic Mu-Negative (MNG) metamaterial with hyperbolic dispersion curve is analyzed rigorously. It is shown that anisotropic MNG metamaterial supports inhomogeneous type of plane wave, a wavelength of which may become infinitesimally short for some special directions of propagation. It is also shown that shortening of a wavelength is actually a consequence...
Using the spectral domain technique in conjunction with finite element slot field expansions, the scattering characteristics of the unilateral finline-coplanar waveguide transition are analysed. Flexible rooftop functions varying in both the transverse and longitudinal directions are used instead of a uniform rooftop function as expansion functions to handle arbitrary slot width structures. A typical...
