Summary: The development of context-aware environments and applications requires a strong connectivity, which calls for new spectral bands and radio resource management functionalities in both current 5G and future 6G wireless communication systems. This presents challenges in implementing wireless transceivers and radiating systems in terms of device integration, miniaturization, and element isolation. This study proposes high-performance miniature devices using metamaterial-inspired complementary resonators, which demonstrate excellent agreement between analytical circuit models and electromagnetic simulations. The design flexibility allows for easy tunability and frequency scalability. However, the presented devices are just a fraction of the potential combinations for integration in future wireless communication systems.

Summary: This paper presents a flexible double-sided attached microwave sensor film for real-time measurement of liquid dielectric constant. The film is composed of a ground film with a nested-complementary split ring resonator (NCSRR) structure and a U-shaped microstrip line film. Two types of microwave sensors are formed by attaching the films to both sides of borosilicate glass and polypropylene beakers. The resonant frequencies of the sensors are linearly and negatively correlated with the dielectric constant of the liquid to be measured.

Summary: In this research, a low-profile, wideband microwave metamaterial absorber with wide-angle and polarization-independent responses was proposed by controlling multiple resistive electric and magnetic resonances. The use of a vertical periodic crossed mesh array improved wide-angle polarization-independent absorption, and a dispersion-engineered design strategy for angular- and polarization-insensitive responses was described with numerical evidence and electromagnetic response behaviors. Both numerical and experimental results showed that the proposed strategy is an effective way to achieve wide-angle and polarization-independent responses in a broadband spectrum, which is promising for various strategic applications.

Summary: The phase transition between vortex generation and spin-Hall shift triggered by varying the incidence angle of a spin-polarized light beam at sharp interfaces has been revealed. The abnormal beam contains wave components with distinct topological properties, generating intrinsic and extrinsic orbital angular momenta. By enlarging the incidence angle, the abnormal beam undergoes a phase transition from vortex generation to spin-Hall shift.

Summary: The manipulation of circularly polarized (CP) electromagnetic (EM) waves is crucial for various applications, but conventional devices have limitations. Pancharatnam-Berry (PB) phase metasurfaces show promising capabilities in controlling CP waves, although they have locked and mirrored functionalities. Spin-decoupled metasurfaces offer a solution by combining orientation-dependent PB phase and dimension-dependent propagation phase, providing a guideline for realizing spin-decoupled functionalities for orthogonal circular polarizations.
