A Low-Profile Decoupling Structure for Mutual Coupling Suppression in MIMO Patch Antenna
IEEE Transactions on Antennas and Propagation, 2021 In this article, a new low-profile decoupling structure originated from the phase shift concept for the patch antenna array is proposed. To clearly illustrate the operation principle, the phase of the signal transmitted from Patch 1 to Patch 2 has been ...

Dynamics of mutually coupled VCSELs [PDF]
SPIE Proceedings, 2004 8 pages, 8 figures.-- Communication presented at: Physics and Simulation of Optoelectronic Devices XII (San Jose, CA, USA, 26 January 2004). We study the dynamics of two Vertical Cavity Surface Emitting Lasers (VCSELs), when they are bidirectionally coupled through the mutual injection of their coherent optical fields.

Decreasing Mutual Coupling in a Phased Array Using a Mutual Coupling Based Element [PDF]
2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019 Generally, mutual coupling substantially affects performance of arrays in both transmit and receive states. This paper is to address this challenge. In this paper, a densely packed S-band circularly polarized (CP) microstrip phased array antenna is designed.

Deep Convolutional Neural Networks to Predict Mutual Coupling Effects in Metasurfaces [PDF]
Advanced Optical Materials, 2021 Metasurfaces have provided a novel and promising platform for realizing compact and high‐performance optical devices. The conventional metasurface design approach assumes periodic boundary conditions for each element, which is inaccurate in most cases ...

Comparing Mutual Coupling of Ring Metamaterial on Square and Vivaldi Array Antennas
Buletin Pos dan Telekomunikasi: Media Komunikasi Ilmiah, 2020 The antenna performance is seen from the S-parameter value. The S-parameter graph can be seen as the return loss (S11, S22) and the mutual coupling (S21, S12) value.

Mutually delay-coupled semiconductor lasers: Mode bifurcation scenarios [PDF]
Optics Communications, 2005 We study the spectral and dynamical behavior of two identical, mutually delay-coupled semiconductor lasers. We concentrate on the short coupling-time regime where the number of basic states of the system, the compound laser modes (CLMs), is small so that their individual behavior can be studied both experimentally and theoretically.

Coherent regimes of mutually coupled Chua’s circuits [PDF]
Physical Review E, 2006 We study the dynamical regimes that emerge from the strongly coupling between two Chua's circuits with parameters mismatch. For the region around the perfect synchronous state we show how to combine parameter diversity and coupling in order to robustly and precisely target a desired regime.
