Large-scale high-density terahertz radiator and receiver Arrays on silicon chips
Electromagnetic (EM) waves in the terahertz (THz) frequency range (usually deαned as from 10⁻¹ THz to 10¹ THz) have important applications in gas sensing, non-invasive imaging, short-range ultra-high-data-rate wireline/wireless communications. Historically, due to their speed limit, silicon-based …

Investigation into a GPS time pulse radiator for testing time-stamp accuracy of a radio telescope
… are aligned to UTC. A portable GNSS time-pulse radiator (GTR) device for testing the time-stamp accuracy was developed. The GTR was calibrated at the National Metrology Institute of South Africa and laboratory characterisation tests measured its RF timing pulse to be 1.32 ± 0.100 µs ahead of the …

Effect of a Dual Loop Thermal Management Arrangement with a Single Module Radiator on Vehicle Power Consumption
A single module radiator within a dual loop vehicle thermal management setup was investigated as a method for reducing the vehicle power consumption when the air conditioner was operating. The cooling fan and the air conditioning compressor consume the most vehicle power within the vehicle thermal …

A 2-D Scalable Third harmonic radiator at 291.3 GHz with -2 dBm of Radiated Power in 22 nm FinFET Technology
… In this work, we present a Terahertz (THz) radiator at 291.3 GHz. The footprint of the unit radiator is half-wavelength at the radiation frequency, which enables 2-D scalability. Passive coupling is implemented between the radiator elements for de-centralized phase locking and free-space …

Quasiparticle beam profile measurements in superfluid helium 3 - B
… the quasiparticle beam profile from a Black-Body radiator and a vibrating wire resonator is measured using a quasiparticle camera which consists of 25 tuning forks. The vibrating wire resonator is found to have a very thinly spread beam at velocities slightly higher than the pair-breaking critical …

The aerodynamics of Formula One car cooling ducts.
… stagnation pressure associated with inclining a radiator within a duct. Inclination loss is divided into incidence lo~s and loss due to the duct shaping immediately downstream of the radiator. An actuator-disc type model of the radiator performance is added to one of the in-house CFD codes. This …

Visualisation of quantum turbulence in superfluid 3He-B using a novel 2D quasiparticle detector
… response to beams generated by the black-body radiator and source wire were performed. We observe that the beam generated by a black-body radiator appears approximately symmetric, consistent with being emitted from a point-source of excitations. In addition to this we find that the profile of …
