Mie-Metamaterials-Based Thermal Emitter for Near-Field Thermophotovoltaic Systems

In this work, we theoretically analyze the performance characteristics of a near-field thermophotovoltaic system consisting a Mie-metamaterial emitter and GaSb-based photovoltaic cell at separations less than the thermal wavelength. The emitter consists of a tungsten nanoparticle-embedded thin film of SiO 2 deposited on bulk tungsten. Numerical results presented here are obtained using formulae...

Full Chip Thermal Simulation

A multilayer, full chip thermal analysis is presented. The design of the chip at functional-block level is directly captured to the simulator, allowing the assessment of the chip layout impact on the system performance due to the elevated operational temperature. The heat generation for each block is obtained by running the circuit-level electrical simulation separately on individual functional...

Engineering On-Chip Thermal Effects

Temperature effects can be used to maliciously affect the behavior of digital crypto-circuits. For example, temperature effects can create covert communication channels, and they can affect the stability of physical unclonable functions (PUFs). This talk observes that these thermal effects can be engineered, and we describe two techniques. The first technique shows how to filter the information...

Efficient thermal infrared emitter with high radiant power

Sensitive and selective gas measurements are crucial for a large variety of applications, e.g., explosion protection. Optical gas detection is usually based on the gas’ absorption of infrared radiation (IR). It is the leading technique in terms of accuracy, reliability, and economic efficiency. Since most gas measurements are made in the two wavelength ranges of (3 . . . 5) and (8 . . . 14) μm,...
