Modeling of novel concept design for extremely small UHF band transmit/receive element based on multiferroics

Carka D., Sepulveda A., Keller S., Carman G.P., New York Institute of Technology, US

Multiferroic heterostructures consisting of a piezoelectric or ferroelectric material and a ferromagnetic material with magnetostrictive properties allow for cross coupling of the electric and magnetic degrees of freedom via strain mediation of the magnetoelectric coupling. [...]

Use of Multiphysics modeling to improve solar thin film performance and manufacture

Jain A., Sanyal J., Ivanov V., Grald E., Mukhopadhyay A., ANSYS, Inc., US

Solar and wind energy are gaining attention for both technology innovation and commercialization, due to the environmental impacts of conventional energy sources, lack of technology breakthrough with hydrogen based systems, and rising oil prices,. Among [...]

Effects of Disorder in Reduced Dimensional and Quantum Electronics

Weaver B.D., Aifer E.H., Naval Research Laboratory, US

We discuss the effect of atomic disorder on electronic systems that operate in either reduced dimension or by quantum-mechanical transport. Systems include high electron mobility transistors, tunnel diodes, superconductors, multiquantum well infrared and ultraviolet detectors, [...]

Spice-like Simulation Using Real Devices Instead of their Mathematical Models

Denisenko V.V., Research Laboratory of Design Automation, RU

Modern Spice-like circuit simulators use increasingly accurate and sophisticated analytical models of components. But the validity of models, that is the probability that the procedure of the model verification is true, still remains very poor. [...]
