We demonstrate a Rydberg atom-based sensor embedded in a parallel-plate waveguide (PPWG) for amplitude and phase detection of a radio-frequency (RF) electric field. This embedded atomic sensor is also capable of receiving modulated communications sig

We demonstrate how Rydberg atoms and the phenomena of electromagnetically induced transparency can be used to aid in the recording of a musical instrument in real time as it is played. Also, by using two different atomic species (cesium and rubidium)

Rydberg atoms have been used for measuring radio-frequency (RF) electric (E)-fields due to their strong dipole moments over the frequency range of 500 MHz-1 THz. For this, electromagnetically induced transparency (EIT) within the Autler-Townes (AT) r

Resonant transmission through a dielectric-loaded slot in a thick conducting diaphragm embedded in a rectangular waveguide is modeled using an analytical approximation based on the slot being small compared to a free-space wavelength. An image theory

With the redefinition of the International System of Units (SI) that occurred in November 2018, there has been much attention on the development of atom-based sensors for metrology applications that are directly linked to the SI. In particular, great

In this paper, we derive an analytical model for plane-wave transmission through a periodic array of dielectric-loaded slots in an infinite metallic screen of finite thickness (a metagrating). We show the existence of (Fano) resonances associated wit

The frequency and incidence-angle dependence of a metagrating consisting of an array of dielectric-loaded slots in a thick perfectly conducting screen is investigated using an analytical method based on a rectangular waveguide model. This model makes

Great progress had been made in the use of Rydberg atoms to detect the amplitude, phase, and polarization of electric fields and modulated signals. This has led to several unforeseen applications, which are discussed here.

Extraordinary transmission through a thick slot in a metallic shield loaded with high-permittivity dielectric is demonstrated using an analytical approximation based on the slot being small compared to a free space wavelength. In addition to previous
