Linear Phase Retrieval for Near-Field Measurements with Locally Known Phase Relations
Alexander Paulus, Jonas Kornprobst, Josef Knapp +1
A linear and thus convex phase retrieval algorithm for the application in phaseless near-field far-field transformations is presented. The formulation exploits locally known phase…
A Combined Source Integral Equation with Weak Form Combined Source Condition
Jonas Kornprobst, Thomas F. Eibert
A combined source integral equation (CSIE) is constructed on the basis of the electric field integral equation (EFIE) to solve electromagnetic radiation and scattering problems con…
A Weak-Form Combined Source Integral Equation with Explicit Inversion of the Combined-Source Condition
Jonas Kornprobst, Thomas F. Eibert
The combined source integral equation (CSIE) for the electric field on the surface of a perfect electrically conducting scatterer can be discretized very accurately with lowest-ord…
An Accurate Low-Order Discretization Scheme for the Identity Operator in the Magnetic Field and Combined Field Integral Equations
Jonas Kornprobst, Thomas F. Eibert
A new low-order discretization scheme for the identity operator in the magnetic field integral equation (MFIE) is discussed. Its concept is derived from the weak-form representatio…
Improved Discretization of the Full First-Order Magnetic Field Integral Equation
Jonas Kornprobst, Alexander Paulus, Thomas F. Eibert
The inaccuracy of the classical magnetic field integral equation (MFIE) is a long-studied problem. We investigate one of the potential approaches to solve the accuracy problem: hig…
Accuracy and Conditioning of Surface-Source Based Near-Field to Far-Field Transformations
Jonas Kornprobst, Josef Knapp, Raimund A. M. Mauermayer +3
The conditioning and accuracy of various inverse surface-source formulations are investigated. First, the normal systems of equations are discussed. Second, different implementatio…
Phase Retrieval for Partially Coherent Observations
Jonas Kornprobst, Alexander Paulus, Josef Knapp +1
Phase retrieval is in general a non-convex and non-linear task and the corresponding algorithms struggle with the issue of local minima. We consider the case where the measurement…
