Electromagnetic fields and their interaction with matter of various shapes and compositions are of fundamental importance in realization of many practical systems. Computational Electromagnetics (CEM) deals with numerical modeling of engineering problems governed by Maxwellâ€™s equations. Practical examples of such applied problems can be found in areas such as radar, wireless communication, remote sensing, biomedical engineering â€“ and the list is by no means exhaustive. Research in CEM at UMKC currently focuses on development of techniques for design and prototyping of ultrawideband microstrip antennas, phased array antennas on Unmanned Aerial Vehicles (UAVs), shipborne Missile Defense Radars and radiation behavior of antennas embedded in composites or metamaterials.
Dr. Deb Chatterjee, Ph.D. conducts research in phased arrays, ultrawideband low-profile microstrip patch antennas. His research on ultrawideband antennas and conformal arrays has been supported in the past by Honeywell Federal Manafacturing and Technologies, Kansas City, Mo. Dr. Chatterjee is currently working on developing modeling techniques for embedded antennas, which has been supported by the Radar Division at the US Naval Research Laboratory, Washington, DC.

Goal: For advanced missile defense radars large antenna arrays are embedded in the inhomogeneous media that are continuously stratified. From a computational point of view, modeling the radiation characteristics of antennas embedded in layered media is a challenging problem that is traditionally addressed by discretizing the continuous media into layers. In the present investigation the phase-integral method has been applied to consider the continuous stratification. The applications of this research effort are in characterizing phased arrays covered by a radome having low scattering cross-sections, and predicting electromagnetic interference (EMI/EMC) effects between embedded antennas on complex shipboard platforms.
