AbstractIn this Phase I Small Business Innovation Research project, we propose to develop a software tool for the modeling of low frequency EMI and coupling in complex shipboard environments. The performance of antenna systems is affected by their mountingplatform. In addition, different antenna systems may couple to each other through the free space or their common platform. The coupling effects have to be taken into account in the antenna design process. Rather than costly antenna placement experimentsand exorbitant coupling measurements, the proposed software provides a virtual environment for simulation of these effects. A hybrid frequency domain and time domain technique has been proposed for efficient full-wave simulation of large-scale shipboardenvironments. The Phase I feasibility study will demonstrate the concept of the hybrid technique for coupling of two antennas on a variety of common platforms. The proposed software tool will be used for the design of phased arrays and other shipboardantenna systems. These types of antennas have a variety of applications in both military and civilian communications and sensing systems.
