Magnetically programmable surface acoustic wave devices for RFID applications

Creator:

Chin, Matthew

Abstract:

Magnetically programmable surface acoustic wave (MP SAW) devices were designed, fabricated and characterized in this thesis using integrated giant magnetoresistive (GMR) bits with interdigital reflectors. This provides a proof of concept of a novel storage element on radio frequency identification tags. Interdigital transducers (IDTs) on a piezoelectric substrate are used...

Masters Thesis
Laser probe for the detection of surface acoustic waves

Creator:

Albers, Emory

Abstract:

The Amplitude and phase of surface acoustic waves can be characterized using a laser beam and photodiode detector. This paper describes a technigue for charactarizing waves using the double photodiode method. This method is a modification of the knife-edge method, and involves focusing a laser beam to a beam spot...

Honors College Thesis
A fabrication study of surface acoustic wave devices for magnetic field detection

Creator:

Chin, Matthew L.

Abstract:

Surface acoustic wave (SAW) sensors are versatile devices that can be configured to sense a variety of measurands such as temperature and pressure. The potential use of surface acoustic wave devices for magnetic field detection is explored in this study. Compared to current magnetic field sensors, a sensor based on...
