Mathematics scholar recognised for Highly Cited Research by international journal


An innovative research paper by Dr Liu Hongyu, Associate Professor of the Department of Mathematics, has been honoured as Highly Cited Research by the international publication Journal des Mathematiques Pures et Appliquees
The paper entitled “Enhanced near-cloak by FSH lining” was one of the five mostly highly cited papers published in the journal from 2014 to mid 2016. 
In his research, Dr Liu says the transformation-optics invisibility cloaking has practical importance but the blueprints for ideal cloaks make use of singular materials, which pose severe difficulties to practical realisation and theoretical analysis. To avoid the singular structures, Dr Liu’s research developed a novel “near-cloaks by non-singular cloaking materials” making use of an elaborately designed FSH-layer lining which can significantly enhance the accuracy of the near-cloak with a sharply quantifying mathematical design.
Dr Liu was honoured to receive the award as recognition of his achievements. He added that invisibility cloaking is an emerging field of research with an enormous potential for growth. The technology could find significant application in many areas of science and technology, such as radar and sonar, medical imaging, harvesting solar energy and earthquake research.
In addition, Dr Liu has been invited to join the Editorial Board of the renowned journal, Inverse Problems and Imaging, with effect from 1 January 2017 for a three-year term.
