We propose a multiband metamaterial absorber consisting of silicon brick array on metal
substrate in infrared range. Using the regular hexagon array of silicon bricks, the absorption …

We report a polarization-independent unnaturally high refractive index metamaterial. It is
found that the effective permittivity of the designed metamaterial can be drastically increased …

A scheme for measuring microwave (MW) electric (E) fields is proposed based on
bichromatic electromagnetically induced transparency (EIT) in Rydberg atoms. A …

Sugarcane bagasse (SB) is a widely available agro-industrial waste residue in China that
has the potential to be converted into a cost-effective and renewable adsorbent. In this study …

The measurement of Rydberg atoms in low-frequency electric fields is hindered due to the
shielding effect of the vapor cell against low-frequency electric fields. This study analyzes …

Quantum electrometric sensing properties of a four-level system are theoretically
investigated for microwave (MW) field measurement in thermal Rydberg atoms. In the …

A nonlinear absorption spectrum is proposed for measuring microwave electric fields with
tunable sensitivity using electromagnetically induced transparency (EIT) in Rydberg atoms …

A dispersion probe of the electric fields of microwaves (MWs) is proposed using double-dark-
state Rydberg atoms with Doppler effects. The MW field splits the atomic absorption …
