In the above article [1], the sentences in introduction were written as “The second method uses multiple omnidirectional antennas [19], [20], [21], [22], among which the antenna in [20] is more typical, where a dual-band horizontally-polarized (HP) omnidirectional antenna based on a normal loop and an Alford loop achieves a cross diameter of $0.3lambda _{mathrm {L}}$ and a gain range of –0.6 to –1.3 dBi. However, this method can only produce a gain range of –2 to –1.3 dBi, which does not meet the gain requirements of modern routers.”

A radially periodic 2-D leaky wave antenna (LWA) with high gain at broadside, reduced sidelobes, and suppressed open-stopband (OSB) is presented in this communication. The antenna is low profile and is defined by a printed, double microstrip bull’s-eye aperture. To support polarization and pattern agility, as well as applications in full-duplex systems and dual-polarization scenarios, the antenna is fed with a compact multislot array at the center of LWA, enabled by substrate integrated waveguide (SIW) technology. When considering differential excitation, the simulations and measurements demonstrate a maximum realized gain of more than 17 dBi at broadside at about 18.4 GHz. Furthermore, due to the suppression of the OSB, persistent broadside radiation is supported from 18 to 19 GHz, along with continuous and sustained directive radiation when the main beam scans through broadside, which is in agreement with leaky-wave (LW) theory. Applications include vehicle antennas and V2X communication systems, satellite connectivity, polarization and pattern diversity scenarios, radar and monopulse systems, as well as 5G/6G wireless communications.

Brewster effect originally refers to the reflectionless transmission of a TM-polarized wave impinging on a lossless dielectric surface at a particular angle. It is generally thought that either the introduction of loss or the change of polarization will break the reflectionless phenomenon. Here, we derive an analytical solution for achieving the generalized Brewster effect in highly dissipative anisotropic media for both TE- and TM-polarized waves. Based on the composite electric and magnetic resonator, we designed a 3-D metasurface with controllable Brewster angles to absorb dual-polarized incident waves without reflection. By stacking massive different metasurface units, each with a deliberately designed Brewster angle, it is possible to achieve omnidirectionally matched absorption for dual-polarized incident waves from a given source. As a proof of concept, we implemented an inhomogeneous planar metasurface. Each unit of this metasurface has a Brewster angle precisely adjusted according to a given line source, which is used to absorb the corresponding impinging wave without reflection. Both full-wave simulations and experimental measurements confirm the nearly omnidirectionally matched absorption. Our work offers a promising approach for applications of metasurfaces in electromagnetic shielding, compatibility, and microwave measurements.

This communication presents a novel deep learning (DL) framework for solving 3-D inverse-scattering problems (ISPs), aimed at reconstructing geometric shapes of perfect electric conductors (PECs) from scattered electric fields. ISPs are inherently ill-posed and nonlinear, challenging both conventional and DL methods. To address this, we propose DeepDPO, a self-supervised DL approach that integrates the reliability of conventional model-based methods with the efficiency of learning-based approaches. The framework employs a probabilistic auto-decoder neural network (PADNN) for continuous geometric representation using a signed distance field (SDF) and incorporates the mesh-based physical optics (PO) method for forward scattering calculations. The reconstructed model is obtained by decoding the object-specific code through the PADNN and optimizing it by minimizing residuals between computed and actual fields. By compressing complex 3-D geometries to compact codes, the PADNN alleviates ill-posedness, while the PO approximation mitigates nonlinearity. Consequently, DeepDPO achieves faster convergence, enhanced accuracy, and eliminates the need for hard-to-obtain electromagnetic data in pretraining. Numerical results demonstrate notable improvements in computational efficiency, accuracy, and the ability to represent complex objects, offering a promising solution for 3-D ISPs with the potential for further integration of physical principles.
