High Performance 2D and 3D Approaches for Adjoint Variable Method Suitable for Inverse Problems
The Transmission-Line Modeling(TLM)is used in the analysis of many electromagnetic problems.Recently,inverse biomedical problems can be solved using TLM method and its sensitivities.During the last few decades,it was recommended to use the Adjoint Variable Method(AVM)over the conventional difference techniques to obtain the sensitivity analysis of engineering problems.In this paper a new formulation of the scattering matrix which needs less storage and speeds up the simulation will be presented.In addition,another technique which joins the scattering and connection processes into a single system of equations is also introduced for the first time.The derivative of the scattering matrix with respect to all parameters will be calculated through some scalar values.These derivatives are required in the AVM technique which in turn is used for the solutions of many inverse problems.
