“…[36] The magnetized plasma has similar properties when the magnetic field is parallel to the structure, which can serve as a topological material, [37][38][39] and the magnetized plasma is usually realized by semiconductor materials. [40,41] The whole structure is terminated with twig-shaped edges that are viewed as the fourth type of edges of the honeycomb lattice. [17] We consider the case when the magnetic field is perpendicular to the structure and transverse magnetic (TM, E z , H x , H y ) modes of the electromagnetic wave will be considered in the following.…”

The twig edge states in graphene‐like structures are viewed as the fourth states complementary to their zigzag, bearded, and armchair counterparts. In this work, a rod‐in‐plasma system in a honeycomb lattice with twig edge truncation under external magnetic fields and lattice scaling is studied and it is shown that twig edge states can exist in different phases of the system, such as quantum Hall (QH) phase, quantum spin Hall (QSH) phase, and insulating phase. The twig edge states in the negative permittivity background exhibit robust one‐way transmission properties immune to backscattering and thus provide a novel avenue for solving the plasma communication blackout problem. Moreover, it is demonstrated that corner and edge states can exist within the shrunken structure by modulating the on‐site potential of the twig edges. Especially, helical edge states with the unique feature of pseudospin‐momentum locking that can be excited by chiral sources are demonstrated at the twig edges. These results show that the twig edges and interface engineering can bring new opportunities for more flexible manipulation of electromagnetic waves.

“…An object at a temperature higher than absolute zero (0 K) continuously radiates electromagnetic waves into free space, and this phenomenon is known as thermal radiation. 1 Therefore, the ability to control thermal radiation in the near-and far-field is essential for some practical applications, including solar energy harvesting, 2,3 infrared camouflage, 4 spacecraft thermal control devices, 5 near-field radiative heat transfer, 6 and passive daytime radiative cooling. 7 According to Planck's blackbody radiation law, the thermal radiation spectra of most objects are mainly located in the infrared bands.…”
