Antenna theory and design
Electromagnetic waves are launched and received by antennas. In response to the needs created by the above-mentioned trends, antenna theory and design has become another main area of research.
The focus is on the development of new analytic and numerical methods of importance for the design of advanced antenna configurations, such as broad-band antenna arrays and antenna arrays conformal to some prescribed (curved) surface. A new area, which is vigorously pursued, is antenna applications exploiting the band structure of photonic crystals.
