Acoustic wave sensors have been proposed for (bio)sensing applications for the past 20 years. One of the most attractive acoustic wave sensor geometries for these applications is the acoustic plate mode (APM) delay line. However, the use of APM delay

For a preliminary inversion of magnetotelluric (MT) data obtained in continental regions it is common practice to assume initially that the underlying structure is one dimensional (ID) so that one of the readily available routines for simple ID inver

The design of an improved acoustic-plate-mode (APM) biosensor is presented. The biosensing element consists of a pair of APM delay lines fabricated on an ZX lithium niobate (LiNbO 3 ) substrate. Each delay line utilizes a single APM and exhibits adja

Justification is given for using the word ‘vector’ (with its mathematical implications) to describe the arrows first employed by Parkinson and Wiese to depict induced magnetic variation fields associated with conductivity anomalies. Despite this,

Surface transverse wave (STW) and shear horizontal acoustic plate mode (SHAPM) geometries have been proposed and demonstrated as potential biochemical sensors. The STW provides simplicity of instrumentation by virtue of its single acoustic mode of op

One of the most important issues in acoustic plate mode (APM) sensor design has been the excitation of a single acoustic mode within the APM spectrum. In order to acheive this selective excitation without incurring high triple transit distortions, si
