Experimental Evidence of Free Carrier Generation in 2D Hybrid Organic–Inorganic Perovskites
Advanced Optical Materials, Volume 14, Issue 14, 10 April 2026.ABSTRACT Despite the significant potential of 2D hybrid organic–inorganic perovskites (2DHOIPs) for high‐efficiency optoelectronics application‐comparable to their 3D counterparts, the fundamental carrier photogeneration remains unclear. In contrast to conventional ultrafast optical property characterization, we use ultrafast photocurrent spectroscopy ...

Microstrip patch array antenna
Electronics Letters, 1984 A microstrip array with mutual coupled rectangular patch radiators is described. By the avoidance of a corporate feeding network, advantages in the antenna performance and design are realisable. Experimental results are presented for both linearly and circularly polarised antennas which demonstrate the usefulness of this special antenna configuration.

Analysis of Circular Polarization of Cylindrically Bent Microstrip Antennas
International Journal of Antennas and Propagation, 2012 When circularly polarized (CP) microstrip antennas are bent, the polarization becomes elliptical. We present a simple model that describes the phenomenon. The two linear modes present in a CP patch are modeled separately and added together to produce CP.

Patch Antennas and Microstrip Lines
, 2010 Microstrip patch antennas have problems of low bandwidths. The aim of this chapter is to show various ways to overcome this problem by using various matching techniques for numerous patch antenna array schemes. Various approaches are used for estimating the figures of merit such as VWSR and the S11 parameter of such antennas.
