High linearity broad-band helix TWTs
… low spectral noise and high efficiency across a broad band. Research has been carried out to achieve these criteria in a helix TWT design. A deeper understanding has been gained on how the basic parameters of a TWT affect its non-linear performance. By selecting and controlling the parameters …

Broad Band Excitation of Rare-Earth Dopants in Chalcogenide Glasses
… characterization has discovered a novel broad bands excitation effect in rare earth-doped chalcogenide glasses. Photoluminescence excitation (PLE) bands with a width of $\sim$450 nm have been observed which efficiently excite a number of rare earth emission lines. This effect is …

A study of Zweig's rule using phi mesons in a broad band neutral beam
A study of Zweig's rule using phi mesons in a high energy photon beam has been performed. Measurement of the ratio sigma (gamma A -> phi pi pi A) / sigma (gamma A -> omega pi pi A) = 0.10 ± 0.02 is taken as evidence that there is not as strong suppression as could be expected. Other ratios show …

Broad-band spectral analysis of a complete sample of type 1 AGN detected by INTEGRAL
… IBIS spectra, providing for the first time a broad-band spectral analysis of a hard X-ray detected complete sample of type 1 AGN. The principal aim of this work is to study the continuum properties of type 1 AGN, i.e. power law slope, reflection fraction and high energy cut-off, and their …

Design of broad-band dual-polarized microstrip patch antennas with high port isolation for millimeter-wave 5G applications
In this thesis, multiple broadband dual linearly polarized antennas are designed covering the frequency band for the next generation of 5G communications around 28 GHz. Dual polarization antennas are employed to increase the capacity of the allocated spectrum through frequency reuse. Techniques for …

State Space Methods Using Biologically-Relevant Generative Models to Analyze Neural Signals
… within and between brain circuits. Co-occurring broad-band, non-periodic signals are also ubiquitous in neural data and are thought to reflect the characteristics of population-level neuronal spiking activity. Identifying oscillatory activity distinct from broadband signals is therefore an …
