Analysis of the raman frequency shifts for the lattice modes and vibrons related to the thermodynamic quantities in the? phase of solid nitrogen
(2013)The thermodynamic quantities of the isothermal compressibility, thermal expansion and the specific heat are calculated here as a function of pressure by using the observed Raman frequencies of the lattice modes and vibrons ... -
Circular high-Q resonating isotropic strain sensors with large shift of resonance frequency under stress
(2009)We present circular architecture bioimplant strain sensors that facilitate a strong resonance frequency shift with mechanical deformation. The clinical application area of these sensors is for in vivo assessment of bone ... -
Electrostatic force spectroscopy of near surface localized states
(Institute of Physics Publishing Ltd., 2005)Electrostatic force microscopy at cryogenic temperatures is used to probe the electrostatic interaction of a conductive atomic force microscopy tip and electronic charges trapped in localized states in an insulating layer ... -
Metamaterial based telemetric strain sensing in different materials
(Optical Society of American (OSA), 2010)We present telemetric sensing of surface strains on different industrial materials using split-ring-resonator based metamaterials. For wireless strain sensing, we utilize metamaterial array architectures for high sensitivity ... -
RF-MEMS load sensors with enhanced Q-factor and sensitivity in a suspended architecture
(Elsevier, 2010-11-09)In this paper, we present and demonstrate RF-MEMS load sensors designed and fabricated in a suspended architecture that increases their quality-factor (Q-factor), accompanied with an increased resonance frequency shift ... -
Simultaneous measurement of multiple independent atomic-scale interactions using scanning probe microscopy: data interpretation and the effect of cross-talk
(American Chemical Society, 2015)In high-resolution scanning probe microscopy, it is becoming increasingly common to simultaneously record multiple channels representing different tip-sample interactions to collect complementary information about the ... -
Time-delay estimation in dispersed spectrum cognitive radio systems
(SpringerOpen, 2010)Time-delay estimation is studied for cognitive radio systems, which facilitate opportunistic use of spectral resources. A two-step approach is proposed to obtain accurate time-delay estimates of signals that occupy multiple ...
