Much of the confusion in the preceding Comment is resolved once the correct origin and definition of the phrase Negative Phase Velocity (NPV) propagation is recognised. Markel's claim that Im (k2t) < o is a predictor for negative refraction is incompatible with taking μ0-1 E × B as the...
The force which acts on an object without coming physically in contact with it is called non contact force. Learn about its types i.e. Gravitational Force, Magnetic Force & Electrostatic Force.
What is critical angle in refraction?Refraction:When light strikes an object it can bounce off of it, pass through it, or be absorbed by it. When light bounces off of an object it is either reflected or scattered, and when light passes through it is either transmitted or refracted. During...
What Is the Difference Between N-Type and P-Type Semiconductors? N-type and P-type semiconductors have different doping processes. N-type semiconductors are doped with elements with extra electrons, which creates a negative charge carrier. Conversely, P-type semiconductors are doped or coated with...

1、What is metamaterial? The first research on metamaterials was on negative refractive index metamaterials. In 1968, the Soviet scientist Veselago first proposed the concept of materials with negative dielectric constant and negative magnetic permeability at the same time, and predicted that these mater...
What is an integer? A simple definition of integers is they are positive and negative numbers along with zero. Integers are not fractional numbers. For example, -10, -5, 0, 5, 10, etc. are integers.
These structures exhibit enhanced capabilities (negative refraction, diffraction-free, and more) for sensing and imaging. As such, these structures offer promising applications in quantum information processing inside optical integrated circuits. Furthermore, hyperbolic superlattices can form from the ...
What is refraction of light? Learn the definition of refraction of light and see examples of resulting phenomena in the natural world. Related to this Question What is the 'normal' in refraction? A direct comparison with a standard is a definition of what?
