Improvement of Electromagnetic Code for Phased Array Antenna Design

Abstract

This is a final report for EOARD grant FA8655-07-1-3059 entitled Improvement of electromagnetic code for phased array antenna design . An existing time domain code for electromagnetic design and analysis of phased array antennas and other periodic structures such as frequency selective surfaces and meta-materials has been improved in several ways. The code which is named PBFDTD (Periodic Boundary FDTD) now handles magnetic materials (lossy and loss-free). Frequency domain surface currents and the electromagnetic field in the computational volume can be visualized. It is now also possible to use the code without the GUI, which for example makes it easier to couple it to stand-alone optimizers. That required, among others, new formats of the input and output files. Several minor improvements of the code have also been done. For example lumped elements in the form of resistors, inductances and capacitances can now be modeled.
