Experiments at Lawrence Livermore National Laboratory's National Ignition Facility (NIF) require breathtaking precision. Each ...

The design and characterisation of a novel dual-band implantable antenna with compact size is presented in this research. The antenna, which is \(5 \times 5 \times 0.635 {\text{mm}}^{3}\) in size and ...

The demand for millimeter-wave (mm-wave) frequencies in wireless communications is continuously growing at a high rate to enable transfer of large-size data at high speed. The frequency band around 28 ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

So I've been familiar with the basics of polarization since forever, but I recently realized circular polarization is a mystery to me. I've heard of it in conjunction with eg satellite broadcasts, but ...

Fast radio bursts (FRBs) are a kind of energetic cosmic radio burst. Though their duration is usually at millisecond scale, their energy (estimated isotropically) reaches 10 ^36 ～10 ^41 erg, ...

These days, when it comes to GPS devices the antenna is typically part of the package. But what better opportunity for [Pepijn] to learn how to make a GPS antenna from scratch for a badge add-on? A ...
