The electric currents induced by infrared radiation incident on optical antennas and resonant structures increase their temperature through Joule heating as well as change their electric resistance through the bolometric effect. As the thermo-electric mechanism exists throughout a distributed bolometer, a multiphysics approach was adopted to analyze thermal, electrical, and electromagnetic effe...

We have designed and developed a new experimental setup, based on the 3ω method, to measure thermal conductivity, heat capacity and electrical resistivity of a variety of samples in a broad temperature range (2−550 K) and under magnetic fields up to 9 T. The validity of this method is tested by measuring various types of metallic (copper, platinum, and constantan) and insulating (SiO2) material...

The problem of thermal energy increased consumption for heating residential buildings is identified. solution this issue to increase the characteristics enclosing wall structures by insulating them with effective heat-insulating materials. results a comparative analysis on quality parameters building materials used envelopes insulation are presented. data facade systems multilayer models’ engin...

The present review article represents a comprehensive study on polymer micro/nanocomposites that are used in high-voltage applications. Particular focus is on the structure-property relationship of composite materials used in power engineering, by exploiting fundamental theory as well as numerical/analytical models and the influence of material design on electrical, mechanical and thermal prope...

Faults and damage in oil-filled power transformers has a devastating effect on the overall reliability of electrical power systems. Several factors, especially electrical and thermal stresses age the transformer and subject them to incipient faults. These faults, if left undetected will cause deterioration and eventually lead to failure of the transformer [1]. The presence of faults such as arc...

We consider the thermal insulation property of homogeneous anisotropically heat-conducting bodies, i.e. those whose thermal tensor (matrix) A is constant throughout the body but not generally a constant times the identity. This anisotropy is a common feature of nanocomposite materials. We propose using the principal Dirichlet eigenvalue λ of the associated elliptic differential operator −∇ · A∇...
