Main goals

The Laboratory, which started around 1965, is a group of about 25 persons,
all working in the microwave and millimeter wave range. Most of the
activities are in the field of microwave communications, with a strong
experimental and technological background. The research extends to
biological materials and systems at microwaves.

Research areas

Three themes are investigated since the start of the Laboratory:
electronics, including active and passive circuits, communications, more
specifically atmospheric transmission, and bioelectromagnetics.

In the field of microwave and millimeter wave electronics, active and
passive circuits, the Laboratory has facilities for measuring circuits up to
110 GHz and for making its own circuits up to 40 GHz, has produced its own
software for synthesizing passive circuits up to 40 GHz, and possesses an
optimization software for active circuits. The main activity is in
developing and testing models at centimeter and millimeter wavelength on
microstrips, slot lines, coplanar strips, coplanar waveguides, and fin
lines. Transitions of various sorts have been modelled and tested, as well
as amplifiers, oscillators, and mixers. Multilayered planar structures as
well as anisotropic layers have been analyzed and modelled. In cooperation
with the Microelectronics Laboratory, silicon-on-insulator transistors are
measured, characterized, and optimized in view of synthesizing microwave
integrated circuits, in particular for mobile telephony. Research is also
led on multi-GHz lightwave communications systems. These research activities
concentrate on electro-optical and opto-electrical transducers, in
particular PIN photodiodes, with as a goal ultra-wideband devices and
circuits. Since 1997, research activities are led on humanitary mine
clearance, specifically in the area of mine detection.

In the field of communications, more specifically atmospheric transmission,
data have been obtained on a permanent basis from the Olympus satellite of
the European Space Agency (12.5, 20 and 30 GHz), using two earth stations
managed by the Laboratory, in cooperation with the Belgian P.T.T.'s.
(Earlier, the Laboratory has been the Belgian participant to the O.T.S.
project of E.S.A., 1978-1983). Studies are led on various phenomena:
scintillation, depolarization, diffusion, diffraction, and site shielding.

The expertise of the Laboratory is in modelling the phenomena, in view of
evaluating the effect on actual communication signals with a wideband point
of view. Theoretical studies have been conducted up to 300 GHz. Comparison
is presently being made between transmission data at millimetric, infrared,
and optical frequencies. Important research activities are led in the field
of mobile telephony and data transmissions, in urban areas.

In microwave bioelectromagnetics, the action of the electromagnetic field on
the nervous system is investigated. The main interest is in the transmission
between the peripheral and the central nervous systems. Reproducible and
quantitative methods have been elaborated, to measure the pain threshold and
the analgesic effect (electrical, biochemical, and electrophysiological).
Fields of digital mobilophony are especially investigated.


The Laboratory disposes of:

-  production facilities to easily and rapidly make planar circuits of
quality controlled up to 40 GHz

-  a set of measuring equipment up to 110 GHz comprising two microwave
network analysers (Wiltron 360B, 40 MHz-40 GHz) with two frequency
extensions (50-75 GHz and 75-110 GHz), a noise measurement system up to 20
GHz, an on-wafer probing system for MMIC measurements up to 40 GHz (Alessi +
Picoprobes) , and a spectrum analyser (HP 26 GHz),

- receivers and transportable beacon generators at 12.5, 20, and 30 GHz, as
well as two radiometers with the data processing capability

-  a facility for bioelectromagnetic measurements.

The Laboratory computer and software equipment includes:

- SUN computers for general purpose

-  HP workstations

-  personal computers (IBM PC's and Apple)

-  laser printers and plotters

-  an optimisation software (OSA 90/HOPE)

-  programming languages (C, C++, Fortran)

-  Excel, Word and Filemaker-Pro on Apple and PC's

-  Matlab.

 Annex. Biographical data.

André Vander Vorst was born in Brussels, Belgium, in 1935. He received the
degrees of Electrical and Mechanical Engineer in 1958 and the Ph.D. degree
in Applied Sciences in 1965 from the Université Catholique de Louvain,
Belgium. In 1965, he received the M.Sc. degree in Electrical Engineering
from Massachussets Institute of Technology, USA. He is associated with the
Université Catholique de Louvain, U.C.L., where he became assistant in 1958,
assistant professor in 1962, associate professor in 1968, and professor in 1972.
>From 1958 to 1964, he worked on fast switching of magnetic cores. With a
NATO fellowship, he was in the US from 1964 to 1966, first at M.I.T., then
at Stanford University, both in the field of radio-astronomy. In 1966, he
founded the Microwave Laboratory at UCL, Belgium, which he is still heading,
starting with research on loaded waveguides and cavities. The laboratory is
presently conducting research on atmospheric transmission and diffraction up
to 300 GHz, the methodology of designing and measuring active and passive
circuits up to 100 GHz, and microwave bioelectromagnetics, namely the
transmission between the peripheral and the central nervous system, using
microwave acupuncture as a stimulus.
He was Head of the Electrical Engineering Department from 1970 to 1972, Dean
of Engineering from 1972 to 1975, Vice-President of the Academic council of
the university from 1973 to 1975, President of the Open School in Economic
ad Social Politics from 1973 to 1987, all at UCL, Belgium. He is a member of
the National Committee of URSI and of various committees on communications,
microwaves, and education. He has been active in IEEE Region 8 as well as in
the European Microwave Conferences. He has authored or coauthored three
textbooks, several chapters, and a variety of scientific and technical
papers in international journals and proceedings. He is a member of Academia
Europaea and The Electromagnetics Academy. He has obtained the Sitel prize
1986, and the meritorious service award of the Microwave Theory and
Technique Society, I.E.E.E. 1994. He is a fellow of the I.E.E.E. 1985 for
his contributions in atmospheric microwave propagation, satellite
communication earth station design, and numerical analysis of microwave

Danielle Vanhoenacker-Janvier was born in Brussels, Belgium, in 1955. She
received the degree of Electrical Engineer in 1978, and the Ph. D. degree in
Applied Sciences from the Université Catholique de Louvain, U.C.L., Belgium,
in 1987.  She is associated with the Université Catholique de Louvain, where
she was assistant from 1979 to 1987 and Senior Scientist from 1987 to 1994.

GHz for more then 15 years and is presently responsible for the research on
transmission. She extended her research activity to microwave circuits in
1989, being mainly involved in the analysis and measurement of microwave
planar active and passive circuits.
