In the fifth-generation (5G) wireless communications, due to advantages such as wide range and low cost, sub-6 frequency band is widely used. It a challenge develop antennas for base stations which are band, high gain compact. this paper, center-fed collinear antenna array with compact size developed based on turnstile antenna. Non-uniform dipole has been used achieve broadband so that disadvan...

Dipole-dipole interactions lead to frequency shifts that are expected limit the performance of next-generation atomic clocks. In this work, we compute dipolar accounting for intrinsic multilevel structure in standard Ramsey spectroscopy. When interrogating transitions featuring smallest Clebsch-Gordan coefficients, find a simplified two-level treatment becomes inappropriate, even presence large...

In Nature, fish have the ability to localize prey, school, navigate, etc., using the lateral-line organ. Artificial hair flow sensors arranged in a linear array shape (inspired by the lateral-line system (LSS) in fish) have been applied to measure airflow patterns at the sensor positions. Here, we take advantage of both biomimetic artificial hair-based flow sensors arranged as LSS and beamformi...

In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...
