Metamaterials and their Applications
(MetaIn-2008)
University of Hyderabad, Hyderabad
18-20th December 2008
Sponsor: Department of Science and Technology, Government of India
Aims and prospects of the Discussion Meeting
The major aim of the DST Discussion Meeting is to gather the leading scientists from all
over the world, engaged in metamaterials research, in order to generate sufficient interest
amongst Indian researchers. Despite the fact that metamaterials research has been identi-
fied as one of the top ten emerging technologies by Technology Review, there is very little
activity as of now in the Indian context. The meeting is to boost research and training
both in fundamental as well as in applied areas. In many Indian Institutes/Universities
there are people with sufficient expertise (both in theory and experiment). One of the
objectives is to attract these scientists into the wonderful world of engineered materials.
List of topics to be covered
• Novel Physics with nano-composites and metamaterials
• Near-field optics and super-resolution
• Plasmonics and photon transport
• Invisibility cloaks
• Heat transfer
• QED with metamaterials
• Fundamental limits in metamaterial devices

A brief overview of the topics to be covered
Metamaterials research was initiated by Sir John Pendry, when he proposed perfect lensing
based on left-handed or negative refractive index materials. Such materials were proposed
by Victor Veselago about three decades back and realized in 2000. It was just the beginning
of an extensive research activity with two-pronged challenge: to understand and predict
the fundamental aspects, as well as to design and fabricate such materials, especially in
the optical domain. Seven years of research on a global scale has added a lot to our
understanding, reaching out from perfect lensing and super-resolution to invisibility cloaks.
Pages from science-fictions are now being revived. Of course a lot more is yet to be achieved.
It is now clear that proper interfacing of nano-technology and metamaterials research
is a must. Sophisticated structures for metamaterials have to borrow from the various
design technologies. A major concern in the semiconductor chip industry is the problem of
dissipation of heat. There have been ideas that use of metamaterials and nano-composites
as substrates can lead to enhanced heat drainage. Most of the research in this direction is
still theoretical in nature asking for experimental input. Another mostly open area is cavity
quantum electrodynamics in the metamaterials environment. Here the goal is to enhance
the spontaneous decay and channelize the fluorescent photons in order to have on-demand
single-photon sources. Over and above the QED aspects one needs to understand the ways
and means of guiding photons in sub-wavelength dimension nano-guides.
Metamaterials have been shown to beat the conventional limits. Research on meta-
materials got the actual boost after it was shown that Raleigh limit can be beaten by a
thin slab of such a material. This undoutedly proved the tremendous potentials of meta-
materials for high density data storage, super-resolution etc. One challenging aspect of
recent research has been how deep one can push the resonance frequency into the optical
region by means of reducing the size of split ring resonators. The reduction of size leads
to a saturation of the resonance frequency, leading ultimately to the vanishing of the nega-
tive magnetic permeability region. Another area with lots of application potential is use of
metamaterials in beating the Chu limit in the fabrication of miniature antennae. Of course,
the ever-present issue relates to the size and shape dispersion of the unit cell SRR (imper-
fections in fabricating the SRR array). Scientists started thinking about broken-symmetry
induced modes of the metamaterials. Can they be used effectively to have additional res-
onances leading to negative permeability. However, more research is needed in order to
have a better understanding of the above phenomena and one of the goals of the meeting
will be to take stock of the current state of the art.
The major scientific aim of the meeting is to capture the evolving state of research after
few lectures covering the basics of metamaterials. Lectures will be delivered by scientists
who initiated the various directions and who are the world leaders. European journal of
physics: Applied Physics has agreed to publish the lectures of the meeting. This meeting
and its outcome is sure to be a great boost for Indian science community.
