We’re sure all radio amateurs must have encountered the problem faced by [Alexandre Grimberg PY1AHD] frequently enough that they nod their heads sagely. There you are, relaxing in the sun on the ...

Recent progress in the fields of magnetic circular dichroism (MCD) and magneto-optical rotatory dispersion (MORD) is reviewed and these techniques are contrasted with those of natural circular ...

There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely perform well. Random pieces of wire may pull in some ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The principle of operation of a wideband crossed-loop magnetic-field direction finder is studied by comparing the bearing determined from the NS and EW magnetic fields at various times up to 155 μs ...

High field: Sawtooth-like inner blades on the cylindrical target induce off-axis charged flows under ultra-intense laser irradiation, driving strong loop currents and generating sub-megatesla magnetic ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...
