Paper Numbering: Proceedings of SPIE follow an e-First publication model, with papers published first online and then in print. Papers are published as they are submitted and meet publication criteria. A unique citation identifier (CID) number is assigned to each article at the time of the first publication. Utilization of CIDs allows articles to be fully citable as soon as they are published online, and connects the same identifier to all online, print, and electronic versions of the publication. SPIE uses a six-digit CID article numbering system in which:

  • The first four digits correspond to the SPIE volume number.

  • The last two digits indicate publication order within the volume using a Base 36 numbering system employing both numerals and letters. These two-number sets start with 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B…0Z, followed by 10-1Z, 20-2Z, etc.

The CID Number appears on each page of the manuscript. The complete citation is used on the first page, and an abbreviated version on subsequent pages.

Authors

Numbers in the index correspond to the last two digits of the six-digit citation identifier (CID) article numbering system used in Proceedings of SPIE. The first four digits reflect the volume number. Base 36 numbering is employed for the last two digits and indicates the order of articles within the volume. Numbers start with 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B…0Z, followed by 10-1Z, 20-2Z, etc.

Introduction

The 2015 Terahertz, RF, Millimeter, and Submillimeter-Wave Technology and Applications VIII conference was divided into 11 sessions reflecting specific categories as follows: Session 1, Terahertz I; Session 2, Terahertz II; Session 3, Terahertz III; Session 4, New Developments in THz, RF, Millimeter-waves, and Sub-Milimeter Waves I; Session 5, New Developments in THz, RF, Millimeter-waves, and Sub-Millimeter-waves II; Session 6, New Developments in THz, RF, Millimeter-waves, and Sub-Millimeter-waves III; Session 7, New Developments in THz, RF, Millimeter-waves, and Sub-Millimeter-waves IV; Session 8, New Developments in THz, RF, Millimeter-waves, and Sub-Millimeter-waves V; Session 9, New Developments in THz, RF, Millimeter-waves, and Sub-Millimeter-waves VI; and a poster session.

There were also a number of excellent poster presentations at this conference.

As in prior Terahertz Technology and Applications conferences, these papers represent a cross section of much of the research work that is being pursued in the technically challenging terahertz spectral and other electromagnetic regions.

In the prior seven years of these Proceedings (SPIE Volumes 6472, 6893 7215, 7601, 7938, 8621, 8624, and 8985, respectively), we (including Dr. Kurt Linden) presented a list of recent technical articles describing significant advances in the terahertz technology. This year, for the interested reader, we also include a list that points to a rather extensive and growing database on the terahertz absorption characteristics of a large number of chemicals given on the website www.thzdb.org. That website, in turn, provides links to related terahertz technology database websites as shown in Table 1.

In the last eight years’ introduction to SPIE Proceedings, Volumes 6472, 6893, 7215, 7601, 7938, 8621, 8624, and 8985, respectively, two tables were included, one summarizing the more common terahertz radiation sources, and the other summarizing the more common terahertz detector types. For the interest of the general reader we again include these tables without updates, other than to note that recent advancements in vacuum electronics BWOs coupled with solid state multipliers have now produced usable power above 2 THz and that devices such as quantum cascade lasers continue to make improvements that encroach upon established high power sources such as carbon dioxide lasers. Due to such advancements, any values listed in Tables 2 and 3 are likely to be bested by new records in a very short time period; however, the sources and detectors listed in Tables 2 and 3 still comprise the majority of those used in the THz regime. Readers of this volume may send additions and enhancements to these tables so that future volumes can continue to provide readers with relevant information on the availability of terahertz sources and detectors. Such suggestions can be sent to sadwick@innosystech.com.
