Plasmonic Metamaterial For Structural Color Printing And Spontaneous Emission Control, Wei Wang

Doctoral Dissertations

”Plasmon polaritons or plasmons are a collective oscillation movement of free electrons in metal at optical frequencies. The frequency-dependent complex dielectric function makes the metal property at optical frequencies behave totally different with that at other spectral ranges with lower frequency such as infrared and microwaves. This novel property makes the so called plasmonics or nanoplasmonics a rapid growing research field over the past few years. Many innovative concepts and applications have been developed such as perfect absorber, structural color printing, and quantum emitter spontaneous emission enhancement.

In this dissertation two of the most important applications will be addressed. The …
