Examples include the following.
1. Mutual coupling between aperture antennas
Relationship of methods for analysing mutual coupling (Bird, 17^{th} Queen Mary & Westfield College Antenna Symposium, University of London, 1112 April 1991).
2. Electromagnetic bandgap components
A 90degree bend in a 3D EBG woodpile waveguide (Weily et.al. Electron. Lett., Vol. 42, 2006, pp. 4243).
3. Mode matching methods
Network representation of an array in terms of scattering matrices (Bird, 17^{th} Queen Mary & Westfield College Antenna Symposium, University of London, 1112 April 1991),
4. Integral equation methods
The magnetic field dH_{s} on a metallic surface due to an elementary magnetic source dM is given by
where T_{zz} etc are the dyadic field components. These can be expressed in complete or asymptotic form for some geometries such as a cylinder (Bird, IEEE Trans. Antennas & Propagation, AP33, 1985, pp. 11081117).
5. Finiteelement Methods
A finite element discretisation with four refined elements including the exterior region R_{1} (Bird, Electron. Lett., Vol. 22, 1986, pp. 697699 ).
