Research ArticleOpen accessIn the keywordsTunability Performance of Reflectarrays Based on Non-Linear Material PropertiesM. Y. Ismail, M. Hashim DahriLimited phase range and narrower bandwidth are the main performance limitations of reflectarray antennas for high gain applications which result in the performance to be restricted particularly in satellite and earth observatory systems. This study provides a thorough investigation on the tunability performance of reflectarrays designed in X-band frequency range using different non-linear dielectric substrates. An investigation of phase agility … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 6 Feb 2013 · 7,450 accessesView PDF Cite

Research ArticleOpen accessIn the abstractREVIEW OF GRAVITATIONAL WAVE DETECTIONS: DYNAMICAL SPACEReginald Thomas CahillThis is a review of the numerous successful gravitational wave detections and the implications for the nature of space and time. The prevailing space time paradigm in physics was founded on the putative "null" results of the Michelson-Morley (MM) 1887 interferometer experiment to detect light speed anisotropy and which resulted in two different new relativity theories: Lorentz relativity (Lorentz, 1904) … …Physics International, Vol. 5, Issue 1 · 27 Mar 2014 · 8,007 accessesView PDF Cite
