larger than the y-orientated magnetic dipoles. The limited volume of a nanostructure
leads to the fact that, y-orientated magnetic dipoles are larger than the x-orientated
ones, leading to the even and odd AMPs for realizing the phase delay of π. Secondly,
every magnetic dipole coupled in an identical antiferromagnetic mode will compete,
leading to the different magnetic momenta that influence the total magnetic field
[15].
4.4 Applications of Chiral Light and Metasurfaces
In this section, we will discuss the applications of chiral light and chiral metasurfaces
in various fields such as detecting the chirality of microscopic objects, optical spin
Hall effects and polarization meta-optics.
