Radio Frequency (RF) Modeling of Layered Composite Dielectric Building Materials

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. A Hybrid techniques is 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. This technique combines the results of periodic full-wave 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 EM.CUBE software foundation, which is already equipped with full-wave FDTD and SBR ray tracing simulation engines.
