Sub-100 nm lithography using ultrashort wavelength of surface plasmons
... In order to utilize ultrashort wavelength of SPs, the SP dispersion curves of four highly conductive metals (silver, aluminum, gold, and copper) are calculated using Eq. (1). As shown in Fig. 2, silver (Ag) exhibits the largest SP wave vector (real part of kSP) at a wavelength of 365 nm (i-line) whe ...

Optical Broadband Angular Selectivity Yichen Shen, Dexin Ye, Ivan Celanovic,
... Methods based on interference and resonance effects have been explored for angular selectivity, but they have limited applications because they are sensitive to frequency. An angularly selective material-system should ideally work over a broadband spectrum. Such a system could potentially play a cru ...
