Nonreciprocity in Bianisotropic Systems with Uniform Time Modulation
Xuchen Wang, Grigorii Ptitcyn, Ana Díaz-Rubio +4
Physical systems with material properties modulated in time provide versatile routes for designing magnetless nonreciprocal devices. Traditionally, nonreciprocity in such systems i…
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,…
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…
Unlimited Accumulation of Electromagnetic Energy Using Time-Varying Reactive Elements
M. S. Mirmoosa, G. A. Ptitcyn, V. S. Asadchy +1
Accumulation of energy by reactive elements is limited by the amplitude of time-harmonic external sources. In the steady-state regime, all incident power is fully reflected back to…
