Abstract
This study investigates the intricate dynamics of energy dissipation in a two-dimensional coplanar magnonic cavity structure, driven by the cavity Lenz effect. We examine the interactions between coupled photonic modes, specifically the dipole (D) and quadrupole (Q) modes, and a magnon mode within the system, aiming to uncover the mechanisms governing dissipation processes. Analysis of the transmission spectrum reveals a fascinating degeneracy between the perpendicular D-mode and the Q-mode, providing new insights into the interplay between dissipation and system behavior. Through theoretical exploration, we detail the resonance phenomena involving the magnon mode, the external photon bath frequency, and the microwave cavity mode, offering a deeper understanding of the complex energy loss dynamics. Our findings emphasize the importance of strategies to minimize energy dissipation and enhance light absorption in magnonic cavities, paving the way for advancements in nanoscale energy harvesting technologies. Moreover, reducing energy loss in these systems will facilitate the development of next-generation optoelectronic and electronic devices.
本研究探讨了在腔体伦兹效应的驱动下,二维共面磁子腔结构中能量耗散的复杂动态。我们研究了耦合光子模式(特别是偶极子(D)和四极子(Q)模式)与系统内的磁子模式之间的相互作用,旨在揭示耗散过程的支配机制。对透射谱的分析揭示了垂直 D 模式和 Q 模式之间迷人的退行性,为耗散和系统行为之间的相互作用提供了新的见解。通过理论探索,我们详细阐述了涉及磁子模式、外部光子浴频率和微波腔模式的共振现象,从而加深了对复杂能量损耗动态的理解。我们的发现强调了在磁子腔中尽量减少能量耗散和增强光吸收的策略的重要性,为纳米级能量采集技术的进步铺平了道路。此外,减少这些系统中的能量损耗将促进下一代光电和电子设备的开发。
