Flexible perovskite solar modules: Fabrication strategies and future prospects
InfoMat, EarlyView.We first systematically summarized the fabrication strategies for flexible perovskite solar modules, including scalable coating and printing, interface engineering, low‐temperature crystallization, and mechanical reliability design. Then we emphasize how process control, material design, and module integration work together to enable high‐performance ...

This paper gives a basic review and a summary of recent developments for leaky-wave antennas (LWAs). An LWA uses a guiding structure that supports wave propagation along the length of the structure, with the wave radiating or “leaking” continuously along the structure. Such antennas may be uniform, quasi-uniform, or periodic.

Review of Recent Advances in the Leaky-Wave Analysis of 2-D Leaky-Wave Antennas
2020 14th European Conference on Antennas and Propagation (EuCAP), 2020Recent developments are reviewed in the area of leaky-wave analysis of two-dimensional (2-D) leaky-wave antennas. Recent results are reviewed in three areas: (1) new beamwidth formulas for 2-D leaky-wave antennas, (2) leakywave analysis of wideband Fabry-Perot cavity antennas, and (3) leaky-wave analysis of 2-D periodic leaky-wave antennas (those that ...

Millimeter waveguides, such as coplanar lines, microstrip lines and dielectric guides, are open structures where energy leakage is bound to occur. This leakage can occur, for example, when there are discontinuities in the guiding structure, or perhaps when the guide is excited in an inappropriate mode.

A History of Leaky Waves and Leaky-Wave Antennas
2019 URSI International Symposium on Electromagnetic Theory (EMTS), 2019The history of leaky waves and leaky-wave antennas is an interesting one, with much of the theory being put on a firm foundation in the 1950s and 1960s by early pioneers such as Nathan Marcuvitz and Arthur A. Oliner. Rapid development of leaky-wave antennas took place after the foundation was established, and the development spread to areas such as ...
