“…In the high-frequency range of 300 kHz to 100 MHz developments have been quite recent and reside within the research community. Accurate theoretical numerical modeling algorithms are available for simulations and interpretation across the entire spectrum (Mackie and Madden, 1993;Pellerin et al, 1995;Pellerin et al, 1997;Alumbaugh and Newman, 1995;Lee et al, 1995, Newmann andNewmann, 1999;Sasaki, 1999, etc. ), but instrumentation suitable for collecting calibrated field data in the important high-frequency range is critically lacking.…”

“…Early Time -High Frequency Two systems should enjoy special attention for attempting to fill the critical gap between GPR and traditional diffusive EM: the high frequency ellipticity (HFE) system (Sternberg zind Poulton, 1994 and the very early time EM system (Pellerin et al, 1994(Pellerin et al, , 1995Wright et al, 1996). A fundamental problem in working in this range is the earth loads the transmitter changing the calibration of the system and hence the ability of quantified interpretation of the data.…”

The electromagnetic integrated demonstration (EMID) is a baseline study in electromagnetic (EM) exploration of the shallow subsurface (e 10 m). Eleven distinct EM systems, covering the geophysical spectrum, acquired data on a grid over the Idaho National Engineering Laboratory (INEL) Cold Test Pit (CTP). The systems are investigated and evaluated for the purpose of identifying and reviewing existing geophysical charactefiation instrumentation (commercial and experimental), integrating those technologies with multi-dimensional interpretational algorithms, and identifying gaps in shallow subsurface EM imaging technology. The EMlD data, are valuable for testing and evaluating new interpretational software, and developing techniques for integrating multiple datasets. The experimental field techniques shows how the acquisition of data in a variety of array configurations can considerably enhance interpretation. All data are available on the world wide web (http://vetem.lbl.gov). Educators and students are encouraged to use the data for both classroom and graduate studies. The purpose of this paper is to explain why, where, how and what kind of data were collected. It is left to the reader to assess the value of a given system for their particular application. Information about the EMID is organized into two general categories: survey description and system evaluation.

“…By the late 90s great interest to fast transient geoelectrics was created by development of registration technology for very early time interval (10 nsec -1 mcsec) and 2-5 nsec step. Unfortunately, the results of appropriate researches have been published in the brief abstracts and reports of limited access (Pellerin, 1994(Pellerin, ,1995Kim, 1996).…”
