Acoustic topological beam nonreciprocity via the rotational Doppler effect. [PDF]
Reciprocity is a fundamental principle of wave physics related to time-reversal symmetry. Nonreciprocal wave behaviors have been pursued for decades because of their great scientific significance and tremendous potential applications.

Remote Measurement of the Angular Velocity Vector Based on Vectorial Doppler Effect Using Air-Core Optical Fiber. [PDF]
Rotational Doppler effect has made tremendous development in both theoretical and applied research over the last decade. Different from the inertial thinking of focusing on the scalar field dominated by helical phase light, we have revealed a vectorial ...

Doppler effect described by the solutions of the Cattaneo telegraph equation. [PDF]
The Cattaneo telegraph equation for temperature with moving time-harmonic source is studied on the line and the half-line domain. The Laplace and Fourier transforms are used.

Cascaded rotational Doppler effect [PDF]
We propose and substantiate experimentally the cascaded rotational Doppler effect for interactions of spinning objects with light carrying angular momentum. Based on the law of parity conservation for electromagnetic interactions, we reveal that the frequency shift can be doubled through cascading two rotational Doppler processes which are mirror ...

The Rotational Doppler Effect of Twisted Photons in Scattered Fields
Along with broad applications of the linear Doppler effect, the rotational Doppler effect (RDE) of a structured light source carrying orbital angular momentum (OAM) has attracted significant attention for applications ranging from optical sensors to ...

Resonant Doppler effect in systems with variable delay. [PDF]
We demonstrate that a time-varying delay in nonlinear systems leads to a rich variety of dynamical behaviour, which cannot be observed in systems with constant delay.

Orbital angular momentum complex spectrum analyzer for vortex light based on the rotational Doppler effect. [PDF]
The ability to measure the orbital angular momentum (OAM) distribution of vortex light is essential for OAM applications. Although there have been many studies on the measurement of OAM modes, it is difficult to quantitatively and instantaneously measure

Rotational Doppler Effect: A Review
Generally, the linear motion between the source of a wave and an observer leads to a linear Doppler effect. It is associated with the linear momentum of the wave. For electromagnetic beams having a circular polarization or an azimuthal phase distribution,

In 1904, the Austrian physicist Fritz Hasenöhrl examined by means of mental experiments the black body radiation in a reflecting cavity. By calculating the work required to keep the cavity moving at constant velocity in opposition to the radiation ...
