This paper proposes a compact non-canonical non-uniform conformal phased array antenna (NNCPAA) attached to an irregular UAV surface to overcome the space and aerodynamic constraints for high-gain, wide-scan applications. The NNCPAA is parametrically deter ...
We report on the performance evaluation of the LEMAC miniature atomic clock, based on the optical-microwave Double-Resonance (DR) scheme, implementing a micro-fabricated Rb vapor cell held inside a custom-designed micro-loop-gap microwave resonator (μ-LGR) ...

This code is used for developing the project entitled “Study on conformal antennas, proof of concept prototype for a UAV”, from the aspects of theory, design, and implementation. This code aims to speed up the investigation of an arbitrary phased array ant ...
Dual resonance Rubidium atomic clock requires a microwave resonator tuned to the frequency of the hyperfine transition of the Rubidium 87 isotope. The vapor cell containing the Rubidium atoms is placed within this resonator. In order to achieve a good cloc ...

Antennas have historically been the most common electromagnetic (EM) technology for wireless communication systems. Antenna as hardware is entirely dependent on the EM properties of the materials used, mostly related to the permittivity and permeability. I ...
We propose strategies for the design of a tuning-free micro-loop-gap resonator (mu-LGR) that provides high magnetic field homogeneity of the TE011-like mode over a broad bandwidth with a high field orientation factor (FOF). This broadband feature allows it ...

Recently, there has been growing interest in the use of metamaterial (MTM)-based lenses, also known as metalenses, as innovative antenna technology. Increasingly widespread applications of metalenses in modern microwave communication and sensing systems ha ...
To miniaturize the double-resonance (DR) rubidium (Rb) vapor-cell atomic clocks, a new type of micro-loop-gap microwave resonator (mu-LGR) is proposed for TE011-like mode where the magnetic field inside the cavity is homogeneous and oriented along its long ...
