Complex source radiation in a cylindrical radome of metal-dielectric grating
(IEEE, 1999)The radiation fields of a line source enclosed in a circular dielectric radorne with grating consisting of an array of thin lossy metal strips are analyzed. The variations of the directivity of the source beam with respect ... -
Interdigital cantilevers for atomic force microscopy
(A I P Publishing LLC, 1996-10)We present a sensor for the atomic force microscope (AFM) where a silicon cantilever is micromachined into the shape of interdigitated fingers that form a diffraction grating. When detecting a force, alternating fingers ... -
One-way reciprocal spoof surface plasmons and relevant reversible diodelike beaming
(American Physical Society, 2013-05-15)One - way excitation of spoof surface plasmons (SPs) and strongly pronounced diodelike extraordinary transmission of linearly polarized waves in the beaming regime can be obtained by combining spoof SPs and cross-polarization ... -
An optical microcantilever with integrated grating coupler
(IEEE, 2009-06)In this paper, we have fabricated an optical cantilever with an integrated grating coupler. We have used an inexpensive and repeatable method for integrating the grating to the silicon cantilever with a microfabrication ... -
Ultrahigh contrast one-way optical transmission through a subwavelength slit
(Springer, 2013)We computationally demonstrate one-way optical transmission characteristics of a subwavelength slit. We comparatively study the effect in single layer and double layer metallic corrugations. We also investigate the effect ...
