Abstract
We present a memory efficient algorithm for the estimation of adjoint sensitivities with the transmission line modeling (TLM) method. Our algorithm manipulates the local scattering matrices to drastically reduce the required storage for problems with lossy dielectric discontinuities. Only one impulse per cell is stored for two dimensional simulations and three impulses per cell are stored for three dimensional simulations. The required memory storage for our impulse sampling approach is only 10% of that of the original TLM-based adjoint sensitivity analysis. The technique is illustrated through two examples including the sensitivity analysis of a dielectric resonator antenna.
