PIERS provides a large international forum to report on the advances in basic research of electromagnetic theory and its applications.
The 1994 Progress in Electromagnetics Research Symposium (PIERS 94) was organized by the European Space Agency on 11--15 July 1994 in Noordwijk, the Netherlands.
While there are many specialized conferences and workshops dealing with a particular aspect of electromagnetics, PIERS distinguishes itself by its broad scope. This fosters interaction between different fields and allows recent progress made in other fields to find its way to new applications. In more than half of the sessions of PIERS 94, distinguished specialists presented their most recent work.
The main topics are:

Electromagnetic theory: computational EM, methods and techniques, applications;
Electromagnetic compatibility: system analysis tools, verification methodology, statistical approaches, biological effects;
Active remote sensing: radar polarimetry, surface and volume scattering, retrieval algorithms, interferometry;
Passive remote sensing: new ways in microwave radiometry and inversion;
Wave propagation: theory, modelling, ionosphere, atmosphere, mobile;
Antennas: theory, microstrip, multi-layer, reflector and array antennas, analysis, synthesis and measurements;
Devices and materials: millimeters, submillimeter, and optical devices, composite and chiral media.


The proceedings are published in the form of a CD-ROM which contains almost 400 contributions. These are stored in PDF format and can be accessed with the Adobe Acrobat Reader (which is also stored on the CD-ROM). This enables the papers to be viewed and searched on Macintosh, PC (both MS-DOS and MS-Windows) and SUN-UNIX computers with a CD-ROM drive, and printed on any kind of printer. The paper equivalent of the CD-ROM would have comprised several thousand pages.
