Nonlinear chiral transport phenomena

Nonlinear fluctuation phenomena in the transport properties of superconductors

There exist a wide temperature region (GiT < T − T c < T √ Gi), where the influence of fluctuations on the thermodynamic properties of superconductors can be taken into account in the linear (Gaussian) approximation, while their influence on the kinetic properties is strongly nonlinear. Maki-Thompson cotribution to conductivity saturates in this region. However, Aslamazov-Larkin contribution be...

Chiral phenomena in toroidal metamaterials

We present the first observation of circular dichroism due to a combination of resonant toroidal dipole and electric quadrupole excitations in a toroidal metamaterial.

Nonlinear phenomena in beamforming

In this paper we present a summary of nonlinear system level problems in beamforming. The paper summarizes first the nonideal phenomena in power amplifiers, mixers, and oscillators. In digital predistortion inversion of the nonlinearity is needed. Not all linear and nonlinear systems are invertible or they may have only a preinverse or postinverse. Commutation is needed in indirect learning arc...
