Frequency synthesiser architecture eliminating high speed frequency dividers for millimetre-wave applications

A frequency synthesiser architecture for millimetre-wave applications is proposed. The architecture is based on a triple-push oscillator, which functions both as a divider and oscillator. Thus, the proposed architecture eliminates the need for injection locked frequency dividers that are the main contributors to the limited tuning capability of millimetre-wave phase-locked loops. Since the prop...

Analysis of millimetre - wave polarization diverse multiple - input multiple - output capacity Nicholas

Millimetre-waves offer the possibility of wide bandwidth and consequently high data rate for wireless communications. For both uniand dual-polarized systems, signals sent over a link may suffer severe degradation due to antenna misalignment. Orientation robustness may be enhanced by the use of mutual orthogonality in three dimensions. Multipleinput multiple-output polarization diversity offers ...

Supermode-density-wave-polariton condensation with a Bose–Einstein condensate in a multimode cavity

Phase transitions, where observable properties of a many-body system change discontinuously, can occur in both open and closed systems. By placing cold atoms in optical cavities and inducing strong coupling between light and excitations of the atoms, one can experimentally study phase transitions of open quantum systems. Here we observe and study a non-equilibrium phase transition, the condensa...
