|
| |
|
| He has worked on various problem connected with linear wave theory in the subsequent time. The idea
| |
| for a website devoted to water waves was his idea.

| Mike's Phd thesis concerned a two-dimensional floating elastic plate which was solved
| |
| using a Green function method. The motivation for the solution was to model ice floe
| |
| and at the time he was ignorant of the engineering applications (e.g. [[VLFS]]).
| |
| Mike independently derived the Green function which
| |
| was well known in water waves and goes back to [[John_1950a| John 1950]].
| |
| The derivation method was copied by [[Squire_Dixon_2000a| Squire and Dixon 2000]]
| |
| (based on a close reading of his Phd thesis) for the case, not of a free surface,
| |
| but for a free surface covered by a plate
| |
| The results
| |
| of this research were publised in the ''Journal of Geophysical Research'' were largely
| |
| ignored by later researchers. His Phd thesis probably had a much greater influence on
| |
| the researchers who followed at Otago and it is continuing to appear in journal citations.
| |
| The solution method using a Green function coupled with a Green function for the plate
| |
| (the later Green function does not extend to three dimensions because of the much
| |
| more complicated boundary conditions which exist). The solution method has been
| |
| superseeded by more efficient methods, most notably the [[Wiener-Hopf]] method developed
| |
| by Tim Williams and the eigenfunction matching method (which applied to
| |
| multiple plates) developed by
| |
| [[Kohout_Meylan_Sakai_Hanai_Leman_Brossard_2006a | Kohout et. al. 2006]].
| |
| | |
| Mike then extended the two-dimensional solution to a three-dimensional circular elastic plate
| |
| ([[Meylan_Squire_1996a|Meylan and Squire 1996]]).
| |
| This solution again used a Green function method coupled with the eigenfunctions for a circular
| |
| plate (which can be computed in exact form, at least up to solving an equation involving
| |
| Bessel functions. The solution method has been superseeded by [[Peter_Meylan_Chung_2004a | Peter, Meylan and Chung 2004]].
| |
| Mike also developed a method to solve for plates of arbitrary geometry, initially using
| |
| a variational method ([[Meylan_2001a|Meylan 2001]]) and later using the [[Finite Element Method]]
| |
| ([[Meylan_2001b|Meylan 2001]].
| |
| | |
| Mike then worked on using the solution for a circular elastic plate to try and construct a model
| |
| for wave scattering in the Marginal Ice Zone ([[Meylan_Squire_Fox_1997a| Meylan, Squire and Fox 1997]]).
| |
| This model was developed independently of the model of [[Masson_LeBlond_1989a | Masson and LeBlond 1989]]
| |
| but shares many similarities with it.
| |
| | |
| Mike then began to work on a very abstract (and difficult problems) of an eigenfunction
| |
| expansion method for the non-selfadjoint operator which arises in the scattering model
| |
| of [[Meylan_Squire_Fox_1997a| Meylan, Squire and Fox 1997]]. This work is still
| |
| unpublished although a paper has been submitted. It is not a problem in water wave theory.
