Geometric calibration of ultrasound transducer arrays is critical to optimizing the performance of photoacoustic computed tomography (PACT) systems. We present a geometric calibration method that is applicable to a wide range of PACT systems. We obta

We summarize recent approaches to estimate electromagnetic fields in an arbitrary two-dimensional scattering domain. Only an estimate of the objects' spatial support in the scattering environment is required in our approach. Using the Huygens' princi

In this article, we propose a method to reconstruct the total electromagnetic field in an arbitrary two-dimensional scattering environment without any prior knowledge of the incident field or the permittivities of the scatterers. However, we assume t

We present a novel method based on Huygens’ principle and compressive sensing to predict the electromagnetic (EM) fields in arbitrary scattering environments by making a few measurements of the field. In doing so, we assume a homogeneous medium bet

We present a method to accurately predict the electromagnetic fields in an indoor setting using a limited number of measurements of scattered electromagnetic fields. We consider a room with a single object inside and a transmitter at the center of th
