Inverse-Designed Narrowband THz Radiator for Ultrarelativistic Electrons

THz radiation finds various applications in science and technology. Pump-probe experiments at free-electron lasers typically rely on THz radiation generated by optical rectification of ultrafast laser pulses in electro-optic crystals. A compact and cost-ef ...

Collapse phenomena of deformed cavitation bubbles

Outi Supponen

Cavitation bubbles are a topic of long-standing interest owing to the powerful phenomena associated with their collapse. Their unique ability to focus energy typically causes damage in hydraulic machinery (turbines, pumps, propellers, ...) but, if managed ...

Determination of the Thermal Roughness Length for a Built Environment

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau

In this study, the scalar roughness for sensible heat in the temperature profile (z0,h) is determined based on direct skin temperature measurements and profiles of wind and temperature in a complex urban environment. Typically, skin temperatures are inferr ...

Determination of Thermal Roughness Length for Complex Urban Areas with High Resolution Meteorological Stations

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau, Olivier Couach

In this study, we determine the scalar roughness for sensible heat in the temperature profile (z0,h) based on direct skin temperature measurements and profiles of wind and temperature in a complex urban environment. Classically, skin temperatures are infer ...

Microcavity light emitting diodes in the visible red and near infrared wavelength range

It was about 125 years ago that the light bulb was commercialized by Thomas Edison. No doubt a brilliant invention at the time, today its low power conversion efficiency is one of the reasons why lighting in the western world has such high energy consumpti ...
