The gyrotropic properties of a rotating magnetized plasma are derived analytically. Mechanical rotation leads to a new cutoff for wave propagation along the magnetic field, and polarization rotation above this cutoff is the sum of the classical magneto-optical Faraday effect and the mechanico-optical polarization drag. Exploiting the very large effective group index near the cutoff, we expose here that polarization drag can be 10^{4} larger than Faraday rotation at GHz frequency. The rotation…

Wave propagation in rotating magnetised plasmas

Wave propagation properties in a medium are fundamentally affected when this medium is moving instead of at rest. In isotropic dielectric media rotation has two noteworthy contributions: one is a

Faraday–Fresnel rotation and splitting of orbital angular momentum carrying waves in a rotating plasma

Rotational Fresnel drag – or orbital Faraday rotation – in a rotating magnetised plasma is uncovered and studied analytically for Trivelpiece–Gould and whistler–helicon waves carrying orbital angular

Cold plasma waves in the chiral Maxwell-Carroll-Field-Jackiw electrodynamics

In this work, we study the propagation and absorption of plasma waves in the chiral Maxwell-Carroll-Field-Jackiw electrodynamics (MCJF). The Maxwell equations are rewritten for a cold, uniform, and

Rotatory power reversal induced by magnetic current in bi-isotropic media

Bi-isotropic media constitute a proper scenario for scrutinizing optical effects stemming from magnetoelectric parameters. Chiral magnetic current is a macroscopic effect arising from the chiral



Giant polarization drag in a gas of molecular super-rotors

Experiments on light dragging in a moving medium laid the cornerstones of modern physics more than a century ago, and they still are in the focus of current research. When linearly polarized light is

Weakly Magnetized, Hall Dominated Plasma Couette Flow.

A novel plasma equilibrium in the high-β, Hall regime that produces centrally peaked, high Mach number Couette flow is described, and a dynamic equilibrium is reached between the amplified (removed) field and extended density gradients.

Electrically controlled terahertz magneto-optical phenomena in continuous and patterned graphene

It is demonstrated, using broadband terahertz magneto-electro-optical spectroscopy, that in graphene both the magnetic circular dichroism and the Faraday rotation can be modulated in intensity, tuned in frequency and inverted using only electrostatic doping at a fixed magnetic field.

Giant gyrotropy due to electromagnetic-field coupling in a bilayered chiral structure.

We report experimental evidence that electromagnetic coupling between physically separated planar metal patterns located in parallel planes provides for extremely strong polarization rotatory power

The rotation of the plane of polarization of light propagating along the axis of rotation of a rotating dielectric medium, as recently measured by Jones (1976), is examined by means of the usual

Artificial Faraday rotation using a ring metamaterial structure without static magnetic field

A metamaterial structure composed of a periodic array of conductive rings including each a semiconductor-based isolator is experimentally shown to produce Faraday rotation. Due to the presence of the

The ferromagnetic Faraday effect at microwave frequencies and its applications: The microwave gyrator

A new microwave circuit element dependent on the Faraday rotation of a polarized wave has been developed. The element violates the reciprocity theorem and, because it shares this property with a

Laser-driven platform for generation and characterization of strong quasi-static magnetic fields

Quasi-static magnetic-fields up to 800 T are generated in the interaction of intense laser pulses (500 J, 1 ns, 10 17 W cm - 2 ?> ) with capacitor-coil targets of different materials. The

Determining the rotation direction in pulsars

It is shown that mechanical-optical rotation in the pulsar magnetosphere affects polarisation in a way which is indiscernible from Faraday rotation inThe interstellar medium for typical GHz observations frequency, but which can be distinguished in the sub-GHz band.
