Resonant Excitation Of Ions In Paul Trap Mass Spectrometer
(2007-12-29)
A Paul trap mass spectrometer has a three-electrode geometry mass analyzer consisting of two identical end cap electrodes and a ring electrode. Traditionally, the two end cap electrodes are electrically grounded and an RF ...
Studies On Surface Plasmon Resonance And Related Experimental Methods Using Fixed Plasmon Angle
(Indian Institute of Science, 2006-03-08)
Surface plasmon waves are transverse magnetic electromagnetic waves propagating along a dielectric-metal interface. These waves can be excited by resonant absorption of electromagnetic radiation leading to surface plasmon ...
Development Of Point-Contact Surface Acoustic Wave Based Sensor System
(Indian Institute of Science, 2007-05-16)
Surface Acoustic Waves (SAW) fall under a special category of elastic waves that need a material medium to propagate. The energy of these waves is confined to a limited depth below the surface over which they propagate, ...
Semi Conducting Metal Oxide Gas Sensors: Development And Related Instrumentation
(Indian Institute of Science, 2007-05-21)
A sensor is a technological device or biological organ that detects, or senses, a signal or physical condition and chemical compounds. Technological developments in the recent decades have brought along with it several ...
Ultrasound Assisted Optical Elastography For Measurement Of Mechanical Properties Of Soft Tissue Mimicking Phantoms
(2009-03-03)
This work describes the development of an optical probe for measuring movement of tissue particles deep inside which are loaded by an ultrasound remote palpation device. The principle of the method is that ultrasound force ...
