—Harmonic generation in the scattered fields pro- duced by a dielectric sphere coated with a time-varying conductive shell is studied using a Mie theory approach hybridized with conversion matrix methods. Analytic results are derived for plane wave incidence as well as general external excitation using transition matrix techniques. An equivalent transmission line approach is also discussed. Numerical examples validate the derived expressions through comparison with purely numerical methods and…

Conversion Matrix Method of Moments for Time-Varying Electromagnetic Analysis
A conversion matrix approach to solving network problems involving time-varying circuit components is applied to the method of moments for electromagnetic scattering analysis, and the computational cost is discussed, along with an analysis of compression techniques capable of significantly reducing computational cost for partially loaded systems.
Using a High-Speed Plasma as a Conducting Channel to Enable a Novel Antenna Approach
We present a modeling technique to describe the behavior of an antenna with time-varying conductivity. The conducting channel of the antenna will consist of a series of individually-controlled plasma
Method of Moments and T-Matrix Hybrid
Hybrid computational schemes combining the advantages of a method of moments formulation of a field integral equation and T-matrix method are developed in this article. The hybrid methods are
Time-Varying Components for Enhancing Wireless Transfer of Power and Information
The relevance of "electromagnetic systems engineered by temporal modulation" from radio frequencies to even optical wavelengths is established and by periodically modulating the mutual inductance between the transmitter and receiver, the fundamental limits of classical wireless power transfer systems can be overcome.
Temporal switching to extend the bandwidth of thin absorbers
Wave absorption in time-invariant, passive thin films is fundamentally limited by a trade-off between bandwidth and overall thickness. In this work, we investigate the use of temporal switching to
Electromagnetic Fields in a Time-Varying Medium: Exceptional Points and Operator Symmetries
In this article, we study the interactions of electromagnetic waves with a non-dispersive dynamic medium that is temporally dependent. Electromagnetic fields under material time-modulation conserve
Dipole polarizability of time-varying particles
Invariance under time translation (or stationarity) is probably one of the most important assumptions made when investigating electromagnetic phenomena. Breaking this assumption is expected to open
