Holographic-Based Leaky-Wave Structures: Transformation of Guided Waves to Leaky Waves
IEEE Microwave Magazine, 2021The term space wave refers to a wave that is propagating through an open medium with a diverging wavefront as it moves away from the source. The term guided wave denotes a variety of wave configurations that are being carried by a closed/open/partially open structure [1].

Propagation characteristics of leaky waves on a 2D periodic leaky-wave antenna
2017 IEEE MTT-S International Microwave Symposium (IMS), 2017A two-dimensional (2D) periodic leaky-wave antenna consisting of a periodic distribution of rectangular patches on a grounded dielectric substrate, excited by a narrow slot in the ground plane, is studied here. The TM0 surface wave that is normally supported by a grounded dielectric substrate is perturbed by the presence of the periodic patches to ...

Higher-Order Cylindrical Leaky Waves—Part I: Canonical Sources and Radiation Formulas [PDF]
IEEE Transactions on Antennas and Propagation, 2019 Radiation from cylindrical leaky waves (CLWs) supported by layered dielectric media is of interest in a variety of current applications. A comprehensive two-part study has been undertaken to investigate the generation and the radiation properties of CLWs

Leaky waves in a heteroepitaxial film
Journal of Applied Physics, 1973Theoretical as well as experimental investigations were carried out for the propagation of leaky waves along an important class of optical thin-film waveguides. For this type of guiding structure which may consist of heteroepitaxial deposition of ZnS or ZnSe on GaAs, the dielectric constant of the thin film is less than that of the substrate ...

The nature of radiation from leaky waves on single- and double-negative metamaterial grounded slabs [PDF]
IEEE MTT-S International Microwave Symposium Digest, 2004 In this work we investigate the dispersion and radiation properties of leaky waves on metamaterial grounded slabs. A simple analysis of the dispersion equation of TE and TM waves supported by such structures reveals that leaky waves of only the proper ...
