    • Design, manufacture and test of a magnetic encoder 

      Gao, Jun (Engineering and Physical Sciences, 2018-09)
      An new eddy current based magnetic position encoder structure is proposed and studied in this thesis. The encoder is composed of one read head and one scale with metal plates placed periodically on a substrate. The ...
    • Analogue gravity approach to the electronic properties of curved graphene 

      Fitzgerald, Liam (Engineering and Physical Sciences, 2019-05)
      The two-dimensional Dirac material graphene can be bent and folded into countless shapes and structures, in which case the low-energy electronic excitations in the material are described by the mathematics of quantum field ...
    • Time-resolved imaging of guided wave phenomena 

      Chandrasekharan, Harikumar K. (Engineering and Physical Sciences, 2018-06)
      In the past decade, increasing demand and rapid developments in classical and quantum sciences resulted in advanced novel multipixel single photon detector arrays engineered on a single electronic chip. Silicon single ...
    • On the characterization of an ElectroHydroDynamic instability patterning (EHDIP) fabrication process for polymer based MEMS 

      Cargill, Scott (Engineering and Physical Sciences, 2017-07)
      This thesis is concerned with the patterning of polymers by ElectroHydroDynamic instabilities (EHDIP). This process represents contactless, photolithography free micromachining ability. A patterned electrode is held above ...
    • Practical unconditionally secure signature schemes and related protocols 

      Amiri, Ryan Philip (Engineering and Physical Sciences, 2018-02)
      The security guarantees provided by digital signatures are vital to many modern applications such as online banking, software distribution, emails and many more. Their ubiquity across digital communications arguably makes ...
