Abstract
Microwave communication systems are used worldwide in applications as varied as weather forecasting, satellite navigation and air traffic control.
Microwave receivers located in Radio Frequency (RF) communication systems contain sensitive components which need to be protected against the potential damage caused by incident electromagnetic (EM) fields. Computational modelling of the devices that protectsuch a receiver is therefore essential to verify their effectiveness and improve their design.
However, current modelling techniques are not capable of providing sufficiently accurate data at all frequencies of interest to be sure that the level of protection is satisfactory. In this thesis, the capabilities of two novel, numerical modelling techniques - the Unstructured Transmission Line Modelling (UTLM) method and the Boundary Element Method (BEM) - are assessed to determine to what extent they can provide this sufficient level of modelling accuracy concerning the impact of waveguide discontinuities that characterise the behaviour of these protection devices.
