Xinna Jiang, Hongquan Jiang, Maojie Zhang, Yang Liu, Xiaolu Feng, Zhan Yq
This study proposes a THz-TDS-based framework for spectral optimisation and polyethylene (PE) ageing identification. First, a filtering-pooling and peak attention network (FPAN) is developed to mitigate water vapour interference and system noise under conventional conditions. By…
