Award of the

Lampard
Prize

for 2009.


The Douglas Lampard Electrical Engineering Rese
arch Prize and Medal for 2009 has been awarded to
Sushim

Roy for his PhD thesis entitled
‘Development of a frequency encoded chipless RFID tag’
. The
work was carried out
under the supervision of Dr Nemai Karmakar.


In the field of remote automatic identification (for logistics, tracking, toll collection etc) Radio Frequency
Identification (RFID) systems offer the advantages over optical barcodes of added security, less hum
an
intervention and non line
-
of
-
sight operation. However the data
-
carrying (IC) chipset in a conventional
RFID tag is comparatively expensive and
hence

the attraction
s

of the technology

are limited
.


Sushim has designed

a
novel chipless RFID tag

based on
robust RF/microwave and antenna engineering
fundamentals. It is a planar multi
-
resonant passive circuit in series with circularly
-
polarized receiving
and transmitting antenn
as. An

antenna in the reader transmits a frequency sweep which is received by the

tag. In the tag the sweep undergoes predetermined processing in the frequency domain, which is the tag’s
signature
, and this is interpreted in the reader. A fully
-
functional 5
-
bit chipless RFID tag has been
fabricated and tested and field trials support

the robustness of the concept. With further development it

is
expected that it will be possible to manufacture the tags inexpensively and that they will be widely used.


Sushim’s
two
examiner
s, Associate Professor Ananda Sanagavarapu of the University of

Technology
Sydney and Professor Jeffrey Fu of the Chang Gung University Taiwan, noted that ‘the thesis constitutes
a significant contribution to knowledge...contains material worthy of publication...and that the format and
literary presentation of the the
sis are satisfactory’. One further comment was

T
he original idea of using
frequency
-
coded structure
s

is interesting and the literature survey of RFID is well written and thorough
’.


Sushim and his co
-
workers have taken out a provisional patent on the tag
. He has also jointly authored
seven papers in refereed journals and 11 conference papers.


The degree of PhD

was conferred on Sushim
o
n

2
nd

June 2009
.

The Prize and Medal will be presented to
Sushim at the SMEEA dinner on 30
th

June 2010.


Sushim comes f
rom Kolkata in India and
obtained his Bachelor
s

degree in Electronics and
Telecommunication Engineering from
the
Bengal Engine
ering College

in June 2003.

H
is fin
al year thesis
was on m
icrostrip antennas and biasing circuits for GaAs FETs.

Following gradu
ation

he worked in
Samtel in India as a high vo
ltage and electronic engineer under

a Graduate Engineering Trainee

scheme
.
Sushim joined Monash University in November 2004 to do research u
nder the guidance of Dr. Nemai

Karmaka
r.
Sushim was a
recipient of M
IPRS and
MGS scholarships from Monash University

during his
PhD candidature
.


On submission of his thesis
Sushim worked for a brief period for

Ingenius (Australia
)
as an electronic
s
engineer

focusing on medical instruments. After that he
re
joined Monash a
s a research fellow unde
r the
supervision of Dr.

Karmakar to develop a frequ
ency encoded chipless RFID

system where the

tags can be
embedded inside

banknot
es. T
he project is funded primarily

by Securency International,

a joint venture
between the Reserve
Bank of Australia and Innovia films. The company currently makes the currency
notes for Australia

and many

foreign nations.


Sushim’s primary area of interest is the development of passive microwave circuits in
the
C band. His
current work involves the de
velopment of chipless RFID tags on flexible polymer substrate
s

that can be
frequency encoded. He is also involved with the development of ante
nnas for the readers of

chipless
RFID tags.

H
e also has other interests in electronic circuit design
.
