dc.description.abstract	In this thesis wave interference effects in structures with parallel transmission paths are examined, particularly with reference to a split waveguide isolator. In this a waveguide divides into two paths. Broadly if waves propagating through the paths are 180° out of phase where the paths recombine they interfere destructively and little energy is transmitted. Firstly a general approach to wave propagation in structures is discussed. Then reflection and transmission matrices for basic elements are found and scattering matrices determined. The latter are assembled such that the behaviour of more complex structures is found. Examples relating to beam vibration are considered.	en
