Beam Squinting Effects in Super Wideband Communication Systems
Sachitha C. Bandara, Peter J. Smith, Erfan Khordad +3
Beam squint, the frequency-dependent shift of the main beam, poses a major challenge for wideband antenna arrays. This paper focuses on the beam squint effects in super wideband (S…
Bridging Qualitative Rubrics and AI: A Binary Question Framework for Criterion-Referenced Grading in Engineering
Lili Chen, Winn Wing-Yiu Chow, Stella Peng +2
PURPOSE OR GOAL: This study investigates how GenAI can be integrated with a criterion-referenced grading framework to improve the efficiency and quality of grading for mathematical…
Target Detection with Tightly-coupled Antennas: Analysis for Unknown Wideband Signals
Erfan Khordad, Peter J. Smith, Sachitha C. Bandara +2
This paper presents analysis for target detection using tightly-coupled antenna (TCA) arrays with high mutual coupling (MC). We show that the wide operational bandwidth of TCAs is…
Rician Channel Modelling for Super Wideband MIMO Communications
Sachitha C. Bandara, Peter J. Smith, Erfan Khordad +2
Recent developments in Multiple-Input-Multiple-Output (MIMO) technology include packing a large number of antenna elements in a compact array to access the bandwidth benefits provi…
