    • Compact high repetition rate mid-infrared solid-state lasers 

      Thorburn, Fiona Elizabeth (Engineering and Physical Sciences Heriot-Watt University, 2019-11)
      The work in this thesis focuses on the development of novel mid-infrared laser sources which are compact, robust and suitable for the generation of ultrafast pulses with GHz pulse repetition frequencies. The motivation ...
    • First steps to carborane frustrated Lewis pair chemistry 

      Benton, Amanda (Engineering and Physical Sciences Heriot-Watt University, 2019-12)
      Chapter 1 provides an introduction to heteroborane chemistry with particular attention on the substitution of Lewis acid and Lewis base groups onto carborane cages. The various methods used to assess Lewis acidity and ...
    • Quantum vacuum radiation in optical media 

      Westerberg, Niclas Kim Lennart (Engineering and Physical Sciences Heriot-Watt University, 2019-10)
      In this thesis we study quantum vacuum radiation. This is the radiation that is emitted due to changes of the electromagnetic vacuum in time. Specifically, we explore the phenomena in optical media at a macroscopic scale ...
    • Deep learning-based person re-identification 

      Borgia, Alessandro (Engineering and Physical Sciences Heriot-Watt University, 2019-10)
      In this dissertation I address the problem of person re-identification for wide-area surveillance applications, in the challenging scenario of an unconstrained network of uncalibrated and non-overlapping cameras. Specifically, ...
    • New feeding networks and planar antenna designs for leaky-wave systems and communication applications 

      Gomez-Guillamon Buendıa, Victoria (Engineering and Physical Sciences Heriot-Watt University, 2019-09)
      The fast development in modern communication systems such as radars, medical imaging, sensors or satellites demands efficient and compact antenna designs that can satisfy the high data throughput and beam scanning requirements. ...
