Cooling efficiency and losses in electrocaloric materials

A figure of merit for assessing the cooling efficiency of electrocaloric (EC) materials is defined, where the caloric properties are taken into account jointly with the material's losses. Using a specifically developed measurement setup, based on…

A Multimaterial Topology Optimization considering the PM Nonlinearity

Density-based topology optimization methodologies in magnetostatics interpolate either the magnetic permeability μ or the magnetic reluctivity ν to define intermediate materials and compute the problem sensitivities. These choices may lack physical…
