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 ...
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 ...
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 ...
This paper discusses several evolved micro-loop-gap microwave resonator designs for chip-scale atomic clock applications. Two different schemes have been investigated to develop the LEMAC (LTF-EPFL Miniature Atomic Clock) based on the optical-microwave dou ...

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 ...
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) ...

We demonstrate and study a microcell microwave atomic clock based on optical-microwave double resonance (DR) interrogation operated in a pulsed Ramsey scheme, called the mu POP clock, based on a microfabricated Rb vapor cell and a micro-loop-gap microwave ...
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 ...
