Diagnostic tools are of fundamental importance in experimental research. In plasma physics, probes are usually used to obtain the plasma parameters, such as density, temperature, electromagnetic fields, and waves. This Review focuses on low-temperatu

Sheaths and associated potential structures in plasmas and resulting instabilities are almost ubiquitous in laboratory plasmas and also frequently found in space plasmas. Here we would like to present a few examples, describe their observations and f

Two new properties of whistler modes have been observed in a large laboratory plasma which are relevant to whistler waves in space plasmas. The first is the reflection of whistler modes by nonuniform magnetic fields whose gradient scale length is com

A review of a deceptively simple topic is presented, i.e., the excitation of whistler modes by antennas. It includes the knowledge of antennas and of the waves and their coupling. This review will show how the research in the last few decades has adv

Electromagnetic waves with helical phase surfaces arise in different fields of physics such as space plasmas, laboratory plasmas, solid-state physics, atomic, molecular and optical sciences. Their common features are the wave orbital angular momentum

Positively biased probes in magnetized plasmas can create several phenomena which are not described by standard probe theories. These include transient currents for pulsed electrodes in the regime of Electron MHD, relaxation oscillations induced by l

The properties of helicon modes in highly nonuniform magnetic fields are studied experimentally. The waves propagate in an essentially unbounded uniform laboratory plasma. Helicons with mode number m = 1 are excited with a magnetic loop with dipole m

In a large laboratory plasma, the properties of whistler modes are investigated in highly nonuniform magnetic fields. In an extension to previous measurements in two dimensions (2D), the present work shows new phenomena such as wave splitting in the

The wave equation for whistler waves is well known and has been solved in Cartesian and cylindrical coordinates, yielding plane waves and cylindrical waves. In space plasmas, waves are usually assumed to be plane waves; in small laboratory plasmas, t

The orbital and spin angular momenta of helicon modes have been determined quantitatively from laboratory experiments. The current density is obtained unambiguously from three dimensional magnetic field measurements. The only approximation made is to
