Angular Anisotropy of Thermoelectric Properties of a Periodic Composite Medium in the Presence of a Magnetic Field
When the magnetic field is strong enough, the effective galvano-magnetic thermoelectric properties of periodical metamaterial exhibit very strong variations with the direction of the applied magnetic field wit...

Enhancement of Power Factor in A Thermoelectric Composite With A Periodic Microstructure
The thermoelectric power factor has been calculated for a two-constituent composite medium, where one constituent is a “high quality thermoelectric” while the other constituent is a “benign metal”, with large ...

Composite Thermoelectrics - Exact Results and Calculational Methods
A theoretical study of composite thermoelectric media has resulted in the development of a number of simple approximations, as well as some exact results. The latter include exact upper and lower bounds on the...

Thermoelectric Properties of Two Component Composites
An explicit expression for the bulk effective thermoelectric coefficient αe of a two component composite is derived. This coefficient is found to depend only on the bulk effective electric conductivity σe and the...

Bulk Effective Moduli: Their Calculation and Usage for Describing Physical Properties of Composite Media
While not telling the whole story, the representation of a composite medium by a homogeneous effective medium is often an excellent approximation for describing its macroscopic physical properties. Modern meth...

Hydrodynamic theory of fourth sound in clamped conditions
The hydrodynamic theory of fourth sound is developed in detail for the cases of a flat capillary and a porous superleak filled with superfluid helium whose normal fluid motion is completely clamped. The attenu...
