Wave propagation in metamaterials mimicking the topology of a cosmic string
Isabel Fernández-Núñez, Oleg Bulashenko
We study the interference and diffraction of light when it propagates through a metamaterial medium mimicking the spacetime of a cosmic string, -- a topological defect with curvatu…
Emergence of Fresnel diffraction zones in gravitational lensing by a cosmic string
Isabel Fernández-Núñez, Oleg Bulashenko
The possibility to detect cosmic strings -- topological defects of early Universe, by means of wave effects in gravitational lensing is discussed. To find the optimal observation c…
Wave diffraction by a cosmic string
Isabel Fernández-Núñez, Oleg Bulashenko
We show that if a cosmic string exists, it may be identified through characteristic diffraction pattern in the energy spectrum of the observed signal. In particular, if the string…
Anisotropic metamaterial as an analogue of a black hole
Isabel Fernández-Núñez, Oleg Bulashenko
Propagation of light in a metamaterial medium which mimics curved spacetime and acts like a black hole is studied. We show that for a particular type of spacetimes and wave polariz…
