Over the last two decades, metamaterials (MMs) and metasurfaces (MTSs) have been used to fabricate innovative antenna designs, offering cost-effective solutions compared to conventional radiating systems. This paper investigates the feasibility of co

We present an experimental validation of the distorted Born iterative method with the two-step iterative shrinkage thresholding (DBIM-TwIST) algorithm for the problem of brain stroke detection and differentiation, using an anatomically accurate, mult

—We assess the application of microwave tomography (MWT) for the detection of axillary lymph nodes (ALNs) in breast cancer patients. We numerically study the effects of limiting angular view in axillary MWT, as probes can only be placed on a limite

We present an initial experimental validation of a microwave tomography (MWT) prototype for brain stroke detection and classification using the distorted Born iterative method, two-step iterative shrinkage thresholding (DBIM-TwIST) algorithm. The val

This work examines the impact of prior information (or “initial guess”) for calibrating a microwave tomography system for brain stroke detection and differentiation, using a multi-layered, anatomically complex head phantom. The imaging algorithm

Brain stroke is an emergency condition that is caused either by a blocked or a burst vessel (ischemic or hemorrhagic stroke, respectively), resulting into abnormal blood supply into the affected area, with severe and sometimes deadly consequences. Ea
