Fano Resonance: An Insight into Electrodynamics
The phenomenon of Fano Resonance represents a fascinating aspect of electrodynamics, showcasing the intricate interplay between quantum states and electromagnetic waves. This concept, initially discovered by Italian physicist Ugo Fano in the 1960s, has since become a cornerstone in the field of optical and electronic research due to its unique characteristics and wide range of applications.
Theoretical Background
At its core, Fano Resonance arises from the interference between a discrete quantum state and a continuum of states. This interaction leads to an asymmetric line shape in the absorption or transmission spectrum, characterized by a sharp peak followed by a steep decline. Mathematically, the Fano resonance profile is described by the formula:
\[ \frac{(q + \epsilon)^2}{1 + \epsilon^2} \]
where ‘ε’ represents the energy detuning normalized to the width of the resonance, and ‘q’ is the Fano parameter, indicating the strength and nature of the interference.
