Broadband Artificial Magnetic Conductors Constructed of Magnetically Coupled Elements [PDF]
2021 15th European Conference on Antennas and Propagation (EuCAP), 2021 An Artificial Magnetic Conductor (AMC) is a type of metamaterial that can be used to enhance the performance in several antenna and microwave design applications. In this work we propose an analytical approach for size and bandwidth optimization of AMCs constructed of magnetically coupled elements Numerical results (obtained using COMSOL) for the ...

Bianisotropic Susceptibility Theory of Artificial Magnetic Conductors
2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI), 2023 Over the past 30 years, Artificial Magnetic Conductors (AMCs) have generated immense interest in the microwave community. However, their description has been restricted to crude RLC design or subsidiary transmission-line network modelling. This paper introduces an electromagnetic theory of AMCs in terms of bianisotropic susceptibilities.

Novel Flexible Artificial Magnetic Conductor [PDF]
International Journal of Antennas and Propagation, 2012 A novel flexible uniplanar AMC design is presented. An AMC prototype is manufactured using laser micromachining and it is characterized under flat and bent conditions by measuring its reflection coefficient phase in an anechoic chamber. The designed prototype shows broad AMC operation bandwidth (6.96% and higher) and polarization angle independency ...

Negative inductance circuits for metamaterial bandwidth enhancement
EPJ Applied Metamaterials, 2017 Passive metamaterials have yet to be translated into applications on a large scale due in large part to their limited bandwidth. To overcome this limitation many authors have suggested coupling metamaterials to non-Foster circuits.
