Optimal design of artificial magnetic conductors including angular response

2006 IEEE Antennas and Propagation Society International Symposium, 2006
In recent years, different solutions have been adopted to realize AMC structures, both with mushroom surfaces [1] and by using planar Frequency Selective Surfaces (FSSs) [2-4]. These screens are suitable for low profile antenna configurations, especially in wireless communication systems [5].

A Compact, Low-Profile Log-Periodic Meandered Dipole Array Antenna with an Artificial Magnetic Conductor

International Journal of Antennas and Propagation, 2018
A compact and low-profile log-periodic meandered dipole array (LPMDA) antenna with an artificial magnetic conductor (AMC) is proposed. For compactness, a meander line configuration is implemented with dipole elements and optimized using a genetic ...

Wide-Band and Low-Profile LTCC Conformal Antenna Array With Mixed Feeding Network

IEEE Access, 2020
As we know, the thickness mainly affects the yield of low-temperature co-fired ceramics (LTCC) device. There is a high risk of cracking for the thick structure in manufacture process especially for the curved one.

Assessment on the Bandwidth of Artificial Magnetic Conductors for Antenna-on-Chip Applications

12th European Conference on Antennas and Propagation (EuCAP 2018), 2018
Artificial magnetic conductors (AMCs) received a lot of attention for Antenna-on-Chip applications. Two different methodologies can be identified in the current research on AMCs for Antenna-on-Chip; the AMC is either fully constructed in the metal stack, or the lossy silicon substrate is included in the AMC design. In this paper, an equation is derived

Vorticity‐Driven µ‐Platelet Rotation and Selective Packing for Vertical Thermal–Electrical Interconnects

Advanced Functional Materials, EarlyView.
We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.

Twin Crystal Moiré Metasurfaces for Crossing Flat‐Band Transport

Advanced Functional Materials, EarlyView.
This study introduces twin crystal moiré metasurfaces, breaking in‐plane symmetry to enable reconfigurable acoustic wave manipulation. By adjusting the twin angle and interlayer twist angle, various combinations of hyperbolic, flat bands, and elliptic states can be synthesized in the system.

Gain Enhancement of Monopole Antenna using AMC Surface

Advanced Electromagnetics, 2018
A CPW rectangular-ring antenna over an Artificial Magnetic Conductor (AMC) is presented in this work. The AMC is a designed as a dual-band structure having an array of unit cells and operates at 2.45GHz and 5.20 GHz. A CPW antenna uses this dual-band AMC

Submicron Metasurface Reconfigured Multiband Smart Windows

Advanced Functional Materials, EarlyView.
This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...

Design and optimization of artificial magnetic conductor for aperture coupled SatCom antenna

2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017
In this study, we propose a single antenna structure that is capable of transmit and receive operations for the entire Ku band, eliminating the use of separate antennas for communication. However, such broadband system demand careful ground plane design for optimum antenna characteristics.
