WebSubwavelength grating pairs were fabricated on both glass and silicon substrates. When coupled together the effective grating period is not subwavelength and can exhibit several diffraction orders. Web1 Jun 2024 · Furthermore, this asymptotic definition of subwavelength resonance reveals that there is a fundamental difference between these resonant modes and those which are not subwavelength, and leads to the following existence result: Lemma 2.3.
Web30 Sep 2014 · Sub-wavelength periodic structures are arrangements of different materials with a pitch small enough to suppress the diffraction effects arising from their periodicity. They have been known in electromagnetism since Hertz carried out his pioneering experiments on radio waves in the late 19th century 1. Web1 Jan 2013 · The ability to control wave propagation is of fundamental interest in many areas of physics. Photonic crystals proved very useful for this purpose but, because they are based on Bragg ...
Web29 Jun 2024 · Reconstruction of light profiles with amplitude and phase information, called holography, is an attractive optical technique to display three-dimensional images. Due to essential requirements for an ideal hologram, subwavelength control of both amplitude and phase is crucial. WebAshwin K. Iyer received the Ph.D. degree in electrical engineering from the University of Toronto, Canada in 2009.
