Examples include the following.

1. Mutual coupling between aperture antennas

Relationship of methods for analysing mutual coupling (Bird, 17th Queen Mary & Westfield College Antenna Symposium, University of London, 11-12 April 1991).

2. Electromagnetic bandgap components

A 90-degree bend in a 3-D EBG woodpile waveguide (Weily et.al. Electron. Lett., Vol. 42, 2006, pp. 42-43).

3. Mode matching methods

Network representation of an array in terms of scattering matrices (Bird, 17th Queen Mary & Westfield College Antenna Symposium, University of London, 11-12 April 1991),

4. Integral equation methods

The magnetic field dHs on a metallic surface due to an elementary magnetic source dM is given by


where Tzz 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, AP-33, 1985, pp. 1108-1117).

5. Finite-element Methods


A finite element discretisation with four refined elements including the exterior region R1 (Bird, Electron. Lett., Vol. 22, 1986, pp. 697-699 ).
