THz-PINNs: Time-Domain Forward Modeling of Terahertz Spectroscopy with Physics-Informed Neural Networks
Pengfei Zhu, Xavier Maldague
Terahertz time-domain spectroscopy (THz-TDS) is a powerful tool for extracting optical and electrical parameters, as well as probing internal structures and surface morphology of m…
Thermal diffusivity measurement based on evaporative cryocooling excitation: Theory and experiments
Pengfei Zhu, Hai Zhang, Stefano Sfarra +4
Photo-thermal methods for measuring thermal diffusivity inherently pose an ill-posed inverse problem, affected by factors such as sample thickness, heating or cooling time, and exc…
A novel IR-SRGAN assisted super-resolution evaluation of photothermal coherence tomography for impact damage in toughened thermoplastic CFRP laminates under room temperature and low temperature
Pengfei Zhu, Hai Zhang, Stefano Sfarra +4
Evaluating impact-induced damage in composite materials under varying temperature conditions is essential for ensuring structural integrity and reliable performance in aerospace, p…
A unified framework for thermal face recognition
Reza Shoja Ghiass, Ognjen Arandjelovic, Hakim Bendada +1
The reduction of the cost of infrared (IR) cameras in recent years has made IR imaging a highly viable modality for face recognition in practice. A particularly attractive advantag…
