Summary on Grant Application Form |
|
Temperature effects in microwave circuits can lead to out of specifications operation or in extreme cases device failure. For example: the gyro magnetic properties of ferrites vary in a nonlinear way with temperature and insulation loads high temperatures can produce thin film cracking. Lumped element components are widely used in microwave networks and for miniaturising MMICs. These are practical examples which require advanced design tools to cater for their hybrid nature. Variational methods are proposed here as a unifying analytic approach which can deal with this class of coupled problem. The work package will examine stationary energy formulations for microwave devices, fields and temperature gradients and develop FE based software for these applications. Special consideration will be given to the requirements of non-reciprocal devices using temperature dependant ferrites and also the situation of hybrid power dividers in stripline beamformers.
