- Near-Field Plasmonic Probe with Super Resolution and High . . .
In this work, we present a plasmonic tip (p-tip) developed by tailoring subwavelength annuli so as to couple internal radial illumination to surface plasmon polaritons (SPPs), resulting in an ultrastrong, superfocused spot
- Dielectric nanohole array metasurface for high-resolution . . .
For the sensing application, we demonstrate a limit of detection (LOD) as low as 1 pg ml for Immunoglobulin G (IgG); for resonant imaging, we demonstrate a spatial resolution below 1 µm and
- Tip-enhanced Raman spectroscopy: Chemical analysis with . . .
Tip-enhanced Raman spectroscopy (TERS), a cutting-edge near-field spectroscopic tool, provides invaluable chemical insight with impressive spatial resolution in chemistry-related fields such as molecular and catalytic systems, surface science, two-dimensional materials, and biochemistry
- High-Resolution Near-Field Imaging and Far-Field Sensing . . .
Electromagnetic (EM) inverse problem for detecting and sensing unknowns has attracted tremendous attention Here, without using bulk lens, a method is proposed to realize both near-field imaging and far-field detection with high resolutions using a novel transmissive programmable metasurface
- Approaches to mid-infrared, super-resolution imaging and . . .
It provides an overview of the different near field microscopy techniques developed to address the problem of chemically imaging specimens in the mid-infrared “fingerprint” region of the spectrum with high spatial resolution
- Design of high-resolution near-field focusing metasurface lens
A high-resolution near-field focusing metasurface lens (MSL) was proposed to meet the high-resolution and miniaturization requirements of focusing devices in the Ka-band passive millimeter wave (PMMW) imaging system
- Very high resolution near-field chemical imaging using an . . .
We show that scanning near-field optical microscopy, in combination with an infrared free electron laser (SNOM-IR-FEL), is able to distinguish between normal and squamous low-grade and
