Near-field measurements are commonly performed in anechoic chambers which limits the flexibility and requires high precision equipment to achieve exact results. We investigate a simple near-field measurement setup that does not use a sophisticated positioning system nor does it operate in a controlled environment. Instead, the probe antenna is moved by an operator person while its position is measured by a laser tracker. Measurement results are shown to illustrate the performance of the system.

The paper presents our work to validate the architecture (software and hardware, including sensors) of ArcTurius Rover. ArcTurius is an autonomous system dedicated to the precise location of survivors after a disaster. To be sure that ArcTurius is adapted to a specific mission, we rely on a set of 3D simulations. In this paper, we focus on finding the best parametrization for a LiDAR sensor. We target to find the best trade-off between the quality of the acquired data and energy consumption.

A new analytical method has been introduced to exactly solve the classical problem of electromagnetic diffraction by a slit. It is faster and easier to implement than the standard solution using Mathieu functions. Moreover, the paper contains a successful comparison of the scattered fields for an incident plane wave with that one obtained for an incident Gaussian beam which is easily modelled by a complex-source beam.

We investigate the solar Type III radio bursts recorded at about 10 AU by Cassini spacecraft. More than 300 bursts have been recorded by the RPWS experiment in the time interval from 01 Jan. 2008 to 31 Dec. 2014. We show that the solar Type III occurrence is mainly depending on the solar activity and also exhibits maxima and minima of detection. The source location of such solar bursts is the interplanetary medium because the dominant emission appears at frequency lower than 2.3 MHz.

In artificial ventilation of neonates uncuffed endotracheal tubes are commonly used. The unknown leakage hampers the detection of spontaneous breathing. A new method to measure respiration by using antennae has recently been presented. A respective setup is investigated numerically and experimentally. Both approaches show that the method seems capable of allowing a contactless triggering to synchronize ventilation. The results are compared to derive a better understanding of influencing factors.

In this paper two different antenna topologies for improving the heart beat and breathing detection of people in their homes is shown. A radar system including these antennas for imaging with digital beamforming algorithms has been developed and presented. Measurements are executed and given in this paper with a conclusion.
