PMID: 27192298
Opt Lett. 2016 Apr 01;41(7):1605-7. doi: 10.1364/OL.41.001605.

We report on a remarkable property of azimuthally (radially) polarized light beams containing a vortex or an orbital angular momentum: upon tight focusing of a first-order vortex beam, the subwavelength spot has a shape of an electric (magnetic) dipole...

In-plane time-harmonic elastic wave motion and resonance phenomena in a layered phononic crystal with periodic cracks.

The Journal of the Acoustical Society of America

Golub MV, Zhang C.
PMID: 25618055
J Acoust Soc Am. 2015 Jan;137(1):238-52. doi: 10.1121/1.4904498.

This paper presents an elastodynamic analysis of two-dimensional time-harmonic elastic wave propagation in periodically multilayered elastic composites, which are also frequently referred to as one-dimensional phononic crystals, with a periodic array of strip-like interior or interface cracks. The transfer...

Dihydrogen bonding in complex (PP3)RuH(η(1)-BH4) featuring two proton-accepting hydride sites: experimental and theoretical studies.

Inorganic chemistry

Belkova NV, Bakhmutova-Albert EV, Gutsul EI, Bakhmutov VI, Golub IE, Filippov OA, Epstein LM, Peruzzini M, Rossin A, Zanobini F, Shubina ES.
PMID: 24369730
Inorg Chem. 2014 Jan 21;53(2):1080-90. doi: 10.1021/ic4026206. Epub 2013 Dec 26.

Combining variable-temperature infrared and NMR spectroscopic studies with quantum-chemical calculations (density functional theory (DFT) and natural bond orbital) allowed us to address the problem of competition between MH (M = transition metal) and BH hydrogens as proton-accepting sites in...

Active Drug-Using Women Use Female-Initiated Barrier Methods to Reduce HIV/STI Risk: Results from a Randomized Trial.

UNLABELLED: Background. We tested an original, woman-focused intervention, based on body empowerment, and female-initiated barrier methods, including the female condom (FC) and cervical barriers. Methods. Eligible women were >= 18 years of age, HIV seronegative, and active drug users,...

pi-shifted Sagnac interferometer for characterization of femtosecond first- and second-order polarization mode dispersion.

Optics letters

Golub I, Simova E.
PMID: 18033334
Opt Lett. 2002 Oct 01;27(19):1681-3. doi: 10.1364/ol.27.001681.

A novel configuration for measuring femtosecond polarization mode dispersion (PMD) with a pi-shifted Sagnac interferometer is studied. The advantages of this configuration include a response that is independent of the orientation of the device under test. This independence allows...

Effective grating theory for resonance domain surface-relief diffraction gratings.

Journal of the Optical Society of America. A, Optics, image science, and vision

Golub MA, Friesem AA.
PMID: 15984484
J Opt Soc Am A Opt Image Sci Vis. 2005 Jun;22(6):1115-26. doi: 10.1364/josaa.22.001115.

An effective grating model, which generalizes effective-medium theory to the case of resonance domain surface-relief gratings, is presented. In addition to the zero order, it takes into account the first diffraction order, which obeys the Bragg condition. Modeling the...

Toward the subdiffraction focusing limit of optical superresolution.

Optics letters

Kalosha VP, Golub I.
PMID: 18087535
Opt Lett. 2007 Dec 15;32(24):3540-2. doi: 10.1364/ol.32.003540.

A superresolving three-zone plate is applied to a Fresnel diffractive lens. It is shown that for radial incident polarization this combination produces a focal spot approaching superresolution allowed subdiffractive limit of 0.36lambda/NA for focusing. For media responsive to longitudinal...

Ring resonator in a Sagnac interferometer as a birefringence magnifier.

Optics letters

Golub I, Simova E.
PMID: 15648647
Opt Lett. 2005 Jan 01;30(1):87-9. doi: 10.1364/ol.30.000087.

A novel birefringence magnification technique that uses a ring resonator in a Sagnac interferometer is proposed and demonstrated. An enhancement factor of 38 was obtained experimentally. The scheme can be used to increase measurement sensitivity to small birefringence and...

Electric birefringence in solutions of high molecular weight ribonucleic acid.

Biophysical journal

Golub EI, Nazarenko VG.

The electric birefringence of low ionic strength solutions of high molecular weight ribonucleic acids from various sources was studied. RNA preparations with a high helical content were found to have negative electric birefringence as a result of the segment...

Nonlinear refraction in CS(2) at 10.6 microm.

The nonlinear refractive index n(2) of CS(2) at 10.6 microm, the value of which is a subject of a recent controversy, is measured by an external self-focusing method. We found that n(2) = (2.1 +/- 0.7) x 10(-11) esu,...
