Underground imaging technology has been functional in the detection of utilities in the
subsurface through land surveying. One way to ensure the quality gathering of data is to …

In this paper, we propose a geometric channel model for air-to-air (A2A) unmanned aerial
vehicle (UAV) communication scenarios. The model is established by incorporating line-of …

A helicopter in flight can be considered an unstable dynamic system with many unwanted
vibrations originating from multiple sources, such as the operation of the engines and …

The mechanical vibration of antenna might cause vibration of the path loss of the electric
wave propagation, especially under high electric wave frequencies. In this paper, the impact …

Developments in drone technology have made them crucial in various fields. Vibrations
caused by external conditions or mechanical failures in a drone's design can significantly …

A torsional-antenna and a log-periodic antenna are used as a source and an analyzer,
respectively, to investigate the possible anomalies of an electro-magnetic field. An …

This paper investigates the generation of passive intermodulation (PIM) in coaxial
connectors during vibration. A series of experiments were designed and the simulation …

An antenna in vibration induces interference on the signals that it transmits. This interference
is significant for millimeter-wave and terahertz systems with high order modulation. To …

The fundamental concept of towed underground imaging is the determination of the
electrical resistivity of the ground to assess the composition and utilities present underneath …

In this paper, we analyze the effects of twisting adouble loop torsional antenna. Its
performance has been evaluated as a function of the twist angle around the symmetry axis …
