Instantaneous Radiation from Time-Varying Electric and Magnetic Dipoles
M. S. Mirmoosa, G. A. Ptitcyn, R. Fleury +1
Radiation from magnetic and electric dipole moments is a key subject in theory of electrodynamics. Although people treat the problem thoroughly in the context of frequency domain,…
Complementary metasurfaces for guiding electromagnetic waves
X. Ma, M. S. Mirmoosa, S. A. Tretyakov
Waveguides are critically important components in microwave, THz, and optical technologies. Due to recent progress in two-dimensional materials, metasurfaces can be efficiently use…
The Software-Defined Metasurfaces Concept and Electromagnetic Aspects
Anna C. Tasolamprou, Alexandros Pitilakis, Odysseas Tsilipakos +17
We present the concept and electromagnetic aspects of HyperSurFaces (HSFs), artificial, ultrathin structures with software controlled electromagnetic properties. The HSFs key unit…
Dynamic meta-atoms
Grigorii Ptitcyn, Mohammad S. Mirmoosa, Sergei A. Tretyakov
Interaction of electromagnetic radiation with time-variant objects is a fundamental problem whose study involves foundational principles of classical electrodynamics. Such study is…
Electromagnetic Aspects of Practical Approaches to Realization of Intelligent Metasurfaces
Fu Liu, Odysseas Tsilipakos, Xuchen Wang +9
We thoroughly investigate the electromagnetic response of intelligent functional metasurfaces. We study two distinct designs operating at different frequency regimes, namely, a swi…
Tunable Perfect Anomalous Reflection in Metasurfaces with Capacitive Lumped Elements
Odysseas Tsilipakos, Fu Liu, Alexandros Pitilakis +8
We demonstrate tunable perfect anomalous reflection with metasurfaces incorporating lumped elements. The tunable capacitance of each element provides continuous control over the lo…
Non-Scattering Multi-Mirror Systems for Field Localization
F. S. Cuesta, V. S. Asadchy, M. S. Mirmoosa +1
Resonators composed of two mirrors, such as Fabry-Perot cavities, provide a simple but effective approach to achieve wave transmission with high finesse. Further increase of the qu…
Software-Defined Metasurface Paradigm: Concept, Challenges, Prospects
Alexandros Pitilakis, Anna C. Tasolamprou, Christos Liaskos +13
HyperSurfaces (HSFs) are devices whose electromagnetic (EM) behavior is software-driven, i.e., it can be defined programmatically. The key components of this emerging technology ar…
Parallel-Plate Waveguides Formed by Arbitrary Impedance Sheets
X. Ma, M. S. Mirmoosa, S. A. Tretyakov
In this work, we introduce and study parallel-plate-waveguide structures that are formed by two penetrable metasurfaces having arbitrary sheet impedances. We investigate the guided…
Parallel-Plate Waveguides Formed by Penetrable Metasurfaces
X. Ma, M. S. Mirmoosa, S. A. Tretyakov
In this paper, we introduce and study parallel-plate waveguides formed by two penetrable metasurfaces having arbitrary isotropic sheet impedances. We investigate guided modes of th…
Physical meaning of the dipole radiation resistance in lossless and lossy media
M. S. Mirmoosa, S. Nordebo, S. A. Tretyakov
In this tutorial, we discuss the radiation from a Hertzian dipole into uniform isotropic lossy media of infinite extent. If the medium is lossless, the radiated power propagates to…
