Michael Meylan is a senior lecturer at the [http://www.newcastle.edu.nz The University of Newcastle].  The wikiwaves site is largely his work. His home page can be found at [http://carma.newcastle.edu.au/meylan]
He completed his Ph.D. under [[Vernon Squire]]
 
in 1993 which was concerned with modelling ice floes using linear wave theory.
 
He has worked on various problem connected with linear water wave theory in the subsequent time.

== PhD Otago 1991 - 1993==
 
Mike's PhD thesis concerned a two-dimensional [[:Category:Floating Elastic Plate|Floating Elastic Plate]] which was solved
 
using a [[Green Function Solution Method]] ([[Meylan and Squire 1994]]). 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 1950]].
 
The derivation method was copied by [[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 published in the ''Journal of Geophysical Research'' and were largely
 
ignored by later researchers. His Phd thesis probably had a much greater influence, through
 
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
 
superseded by more efficient methods, most notably the [[:Category:Wiener-Hopf|Wiener-Hopf]] method developed
 
by [[Tim Williams]] and the [[:Category:Eigenfunction Matching Method|Eigenfunction Matching Method]]
 
(which applied to multiple plates) developed by [[Kohout et. al. 2006]].
 
 
 
== Post-Doc in Otago 1994 - 1996 ==
 
 
 
[[Image:Mikem2006.jpg|thumb|right|Photo taken in 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 The solution method has been superseded by [[Peter, Meylan, and Chung 2004]].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 2002]]).
 
 
 
== Post Doc Auckland 1996 - 1998 ==
 
Mike then worked on using the solution for a circular elastic plate to try and construct a model
 
for [[:Category:Wave Scattering in the Marginal Ice Zone|Wave Scattering in the Marginal Ice Zone]]
 
([[Meylan, Squire, and Fox 1997]]).
 
This model was developed independently of the model of [[Masson and LeBlond 1989]]
 
but shares many similarities with it.  
 
 
 
Mike then worked on a very abstract problem concerning the eigenfunction
 
expansion method for the non-selfadjoint operator which arises in the scattering model
 
of [[Meylan, Squire, and Fox 1997]]. This is a problem in water wave theory.
 
 
 
==Massey University 1999 - 2003 ==
 
 
 
Mike began working on the [[:Category:Time-Dependent Linear Water Waves|Time-Dependent Linear Water Wave]] problem.
 
He solved for the time-dependent motion of a [[:Category:Floating Elastic Plate|Floating Elastic Plate]]
 
assuming [[Shallow Depth]]. The solution was found using a [[Generalised Eigenfunction Expansion]]
 
and as a sum over [[Scattering Frequencies]] ([[Meylan 2002]]). This lead to a collaboration with
 
[[Christophe Hazard]] and to a solution of the problem of a [[:Category:Floating Elastic Plate|Floating Elastic Plate]]
 
on [[Finite Depth]] in the time domain.
 
 
 
[[Cynthia Wang]] worked with Mike as a masters (2000) and PhD student (2001-2003). Her master thesis concerned
 
wave scattering by a [[:Category:Floating Elastic Plate|Floating Elastic Plate]] on water of [[Variable Bottom Topography]]
 
([[Wang and Meylan 2002]]). Cynthia's PhD concerned a higher-order
 
coupled [[:Category:Boundary Element Method|Boundary Element Method]] [[Finite Element Method]] for the three-dimensional
 
[[:Category:Floating Elastic Plate|Floating Elastic Plate]] ([[Wang and Meylan 2004]]) and applied this
 
method to the problem of an [[:Category:Infinite Array|Infinite Array]]
 
of [[:Category:Floating Elastic Plate|Floating Elastic Plates]]
 
([[Wang, Meylan, and Porter 2006]]).
 
 
 
Mike developed a method to solve for multiple floes using an extension of the method
 
of [[Meylan 2002]]. This was not published but was used to test the
 
multiple floe scattering method which was developed with [[Malte Peter]] using [[Kagemoto and Yue Interaction Theory]]
 
which was developed during his masters in 2002.
 
Specifically, in [[Peter and Meylan 2004]] the [[Kagemoto and Yue Interaction Theory]] was extended
 
to infinite depth and a coherent account of the theory for bodies of arbitrary geometry was given.
 
This work required the development of very sophisticated wave scattering code for bodies of
 
arbitrary geometry. As a direct result of this work a new expression for the [[Free-Surface Green Function]] was
 
developed and this was published separately ([[Peter and Meylan 2004b]]).
 
 
 
Mike also revisited the problem of a [[Circular Floating Elastic Plate]] and developed a method
 
based on the [[:Category:Eigenfunction Matching Method|Eigenfunction Matching Method]] ([[Peter, Meylan, and Chung 2004]]).
 
Rike Grotmaack worked with Mike for an honours project in 2002 on [[Wave Forcing of Small Bodies]]
 
([[Grotmaack and Meylan 2006]])
 
 
 
== Auckland 2003 - present ==
 
 
 
[[Malte Peter]] and Mike have continued to work together and have developed an alternative method
 
for the [[:Category:Infinite Array|Infinite Array]] based on [[Kagemoto and Yue Interaction Theory]]
 
([[Peter, Meylan, and Linton 2006]]). This method has been recently
 
extended to a [[Semi-Infinite Array]]. He has continuted to work of [[:Category:Wave Scattering in the Marginal Ice Zone|Wave Scattering in the Marginal Ice Zone]]
 
and has developed a model with [[Alison Kohout]]. This model is based on the multiple
 
[[:Category:Floating Elastic Plate|Floating Elastic Plate]]
 
solution using the [[:Category:Eigenfunction Matching Method|Eigenfunction Matching Method]]
 
([[Kohout et. al. 2006]]). He is presently
 
working on a theory based on [[Scattering Frequencies]] with [[Rodney Eatock Taylor]].
