Abstract
The objective of this SBIR project is to develop a software tool for electromagnetic modeling of layered composite dielectric building materials as well as algorithms which would enable imaging through such structures by mitigating their image distorting properties. Two hybrid techniques are proposed for the calculation of the transmissivity matrix of complex, inhomogeneous, layered walls with arbitrarily shaped periodic inserts such as seen in rebar and cinder block concrete walls. The first method utilizes a 3-D volumetric integral equation using doubly infinite periodic dyadic Green’s functions. The second technique combines the results of periodic FDTD simulation of the unit cell with an iterative ray tracing algorithm to account for finite-size structures with edge and corner effects. We propose to build these tools based upon our EMCUBE software foundation, which is already equipped with full-wave FDTD and SBR ray tracing simulation engines.
