2020 IEEE USNC-CNC-URSI North American Radio Science Meeting (Joint with AP-S Symposium).
Antenna size increases with wavelength in order to maintain the radiation efficiency so, for low frequencies, grows prohibitively large. Because real estate is at premium in any platform, such restrictions produce electrically small antennas with low

The integration of wide-band high efficiency antennas into conducting airframes especially at low frequencies is very difficult for two reasons: (1) Such antenna need to be large and cannot be protruding out of the airframe, (2) because most airframe

Structural health monitoring (SHM) enables wide-area, in situ, and continuous evaluation of the health of mechanical, civil, and aerospace structures to detect the existence, location, and severity of damage. In this paper, we introduce a sparse and

There are two national facilities in the US that can meet the stringent RCS test requirements of the government for classification, size and fidelity of the data. Characterization of each object takes a long time and slows down research and developme

A figure of merit (FoM) is proposed for fair comparison of various computational electromagnetics solvers. This FoM could be formulated in various fashions depending on what is being evaluated and this paper concerns itself primarily with the FE-BI/F
