ElectroMagnetic Drives & Beam Propulsion Technology Special thanks to Dr. Paul LaViolette for his hard work and research into RocketDyne, Project SkyVault, Microwave Phase Conjugation, etc. This video explains EM Drive technologies such as that featured on as well as those covered in much more explicit detail in "Secrets of Antigravity Propulsion" by Paul LaViolette. New From AlienScientist! Barium Titanate is a type of metamaterial that is added to the paint of stealth aircraft to make them more radar absorbant, because the compound is meta-active (has a negative permittivity and permeability) for frequencies in the radar range. Some compounds such as Gold have a negative permeability but a positive permittivity. This property gives gold it's yellowish metallic hue. My Website is currently undergoing development, but I am working with another individual who has secured the domain names for .org .net and .info I am hoping to have the site up by New Years... but we'll see.

Anisotropic dielectric permittivity: tetragonal-cubic phase transition in barium titanate A thin section of barium titanate is viewed between crossed-polars, Initially, the sample is below the transition temperature, and since the domains of the anisotropic tetragonal phase exhibit birefringence, it is brightly coloured when viewed between crossed-polars. When the sample reaches the transition temperature, the isotropic cubic phase forms, which appears black. From TLP: Introduction to Anisotropy, Courtesy of DoITPoMS, The University of Cambridge.

Relative Dielectric Permittivity Relative Dielectric PermittivityRelative dielectric permittivity (or dielectric constant) of a medium ? is a dimensionless physical quantity characterizing the properties of an insulating (dielectric) medium. It is related to the effect of dielectrics polarization under the influence of an electric field.It shows in how many times the strength of electrostatic interaction in the medium is less than the interaction strength in vacuum. The relative permittivity of air and of the majority of other gases under normal conditions is close to unity (because of their low density). For most solid or liquid dielectrics relative permittivity ranges from 2 to 8 (for a static field).Dielectric constant of water in a static field is quite high, about 80. This value for substances with high electric dipole molecules is also quite high. The relative permittivity of ferroelectrics is tens or even hundreds of thousands.Relative permittivity ? of a substance can be determined by comparing the capacitance of a test capacitor with this dielectric and the capacitance of the same capacitor with vacuumDielectrics permittivity is one of the key parameters in development of electric capacitors. Using materials with high dielectric constant can significantly reduce the physical size of capacitors.Capacitance of a condenser is determined by the following formula:where ?r is dielectric constant of the material between the plates,?o is the electric constant, S is the area of the capacitor plates, d is ...
