A wideband printed ridge gap waveguide 4x4 Butler matrix at 30 GHz is presented. The
printed ridge gap technology is used as it has very low losses and supports the propagation …

In photoacoustic tomography (PAT) systems, the tangential resolution decreases due to the
finite size of the transducer as the off-center distance increases. To address this problem, we …

We present a general theory of the holographic image reconstruction with linear frequency
modulation (LFM) radars. For the first time, the system limitations in terms of the object extent …

We present a novel real-time image reconstruction method processing linear frequency
modulated (LFM) signals. The method exploits the principles of the Fourier-space scattered …

Based on multiple-input-multiple-output (MIMO) arc array, this contribution resolves the
azimuth aliasing limitations of Fourier-based imaging applied to optimized subsampled …

This article focuses on analyzing the aliasing artifact in millimeter-wave imaging systems,
with a special focus on multistatic arrays. The current framework to analyze the behavior of …

Microwave tomography (MWT)-based control is a novel idea in industrial heating systems
that demands fast data acquisition (DAQ) and real-time imaging algorithms. Uniform …

In this paper, we propose a novel approach for circular Multiple-Input Multiple-Output
(MIMO) array imaging, termed the Partial Equivalent Method (PEM), aimed at sidelobe …

This article focuses on dealing with aliasing artifacts in millimeter-wave imaging systems. To
address the challenges and complexities of designing multistatic arrays, sparse …

This study was aimed at investigating the diagnostic value of MRI based on K‐space data
reconstruction algorithm for anterior cruciate ligament (ACL) injury of knee joint and the …
