Current imaging technology for concealed weapon detection in the millimeter-wave (mm-
wave) and terahertz ranges is traditionally limited to a single type of sensor. In this paper, a …

Most terahertz (THz) radar systems can only work in the near-field region, because the THz
source power is limited and the size of the target scattered near field is up to tens of …

In the fast-paced field of human-computer interaction (HCI) and virtual reality (VR), automatic
gesture recognition has become increasingly essential. This is particularly true for the …

With the increasing popularity of human-computer interaction applications, there is also
growing interest in generating sufficiently large and diverse data sets for automatic radar …

State-of-the-art personnel security screening based on microwave imaging technology
heavily relies on threat detection models created by using supervised machine learning …

Terahertz (THz) radar system can realize high-resolution imaging benefits from its
advantages, such as wide bandwidth and short synthetic aperture time. However, due to the …

Measuring in real-time two-phase flow composition of a mixed fluid having high gas void
fraction (GVF) remains a challenging task in oil-gas fields. Such fluid is abundant in gas …

In the past decades, monostatic security screening radars in the millimeter and submillimeter
wave bands have progressed into feasible threat detection prototypes. Although these …

This article presents a physical optics-based simulator for the analysis of terahertz (THz)
imaging systems. The simulation starts by calculating the electromagnetic interactions inside …

We show the diffuse and specular reflection images of defective foams placed on iron plates,
which are obtained by a bifocal active imaging system at 0.22 THz. Foam materials studied …
