Detection of Calcium-induced morphological changes on RBCs by digital holographic microscopy and blinking optical tweezers

Rad, V. F.; Tavakkoli, R.; Moradi, Ali-Reza; Anand, A.; Javidi, B. (IEEE, 2016)

Ca+2 level in the circulating red blood cells (RBCs) takes part not only in controlling biophysical properties, but also affects the membrane composition, and its morphological and rheological properties. Excessive ...

Electronic transmittance phase extracted from mesoscopic interferometers

Tolea, M.; Moldoveanu V.; Dinu I.V.; Tanatar, Bilal (2012)

The usual experimental set-up for measuring the wave function phase shift of electrons tunneling through a quantum dot (QD) embedded in a ring (i.e., the transmittance phase) is the so-called 'open' interferometer as first ...

Ionospheric total electron content estimation using IONOLAB method

Nayir, H.; Arıkan, F.; Erol, C. B.; Arıkan, Orhan (IEEE, 2007)

Ionosphere which is an important atmospheric layer for HF and satellite communications, can be investigated through Total Electron Content (TEC). Global Positioning System provides cost-effective means for TEC estimation. ...

Microsphere-Assisted Super-Resolved Mirau Digital Holographic Microscopy for Cell Identification

Aakhte, M.; Abbasian, V.; Akhlaghi, E. A.; Moradi, A. R.; Anand, A.; Javidi, B. (OSA - The Optical Society, 2017)

In this paper, we use a glass microsphere incorporated into a digital holographic microscope to increase the effective resolution of the system, aiming at precise cell identification. A Mirau interferometric objective is ...

Multimode pumping of optical parametric oscillators

Marshall, L. R.; Kaz, A.; Aytur, O. (Institute of Electrical and Electronics Engineers, 1996-02)

Calculations suggest that optical parametric oscillators (OPO's) can be efficiently pumped using multimode, divergent pump sources. The influence of pump beam divergence and mode structure upon OPO performance is measured ...

Observation of negative refraction and negative phase velocity in true left-handed metamaterials

Özbay, Ekmel; Soukoulis, C.M. (IEEE, 2007)

We report a true left-handed (LH) behavior in a composite metamaterial consisting of periodically arranged split ring resonator (SRR) and wire structures. The magnetic resonance of the SRR structure is demonstrated by ...
