This paper reports measurements of both the spectral and specular thermal radiation emission characteristics of very regularly microconfigured grooved surfaces in a silicon substrate at 300 and 400°C. The resulting surfaces were phosphorus-doped, to assure the dominance of the emission from the material near the sample surface. The samples had groove depths H of zero for a reference, to 42 μm, and widths L = 12.6 to 14 μm. The geometry repeat distance was 22 μm, or 455 grooves per cm. The grooves correspond directly in size to the band of principle emission wavelengths λ that arises at these temperature levels. The measurements show strong spectral effects for normal emission, including highly favored frequencies, for H > λ. This suggests a cavity “organ pipe” mode of emission. Similar, though modified, effects were found in directional emission, away from the normal. There also were strong polarization effects, with the cross-groove polarization mode dominant. The spectral and specular measurements are compared with calculations of the classical kind, which tacitly assume that λ < < H = 0(L).

The second edition of The Baroque Clarinet (1992) is a history of the clarinet and chalumeau from antiquity to 1760 in six chapters: “Origins of the Chalumeau,” “Music for the Chalumeau,” “The Earliest Clarinets,” “Playing Techniques for the Baroque Clarinet,” “Music for the Baroque Clarinet,” and “Baroque Clarinet in Society.” There are five appendices: four checklists of extant chalumeaux, extant clarinets, chalumeau music and sources from 1694 to 1780, clarinet music and sources from about 1715 to 1760; and a fifth of chalumeau and clarinet concerts, rehearsals, and clarinets for purchase in newspaper advertisements from 1718 to 1760. The second edition has significant additions of makers, players, music, and iconography, that last in a chapter called “The Baroque Clarinet in Society.” Topics discussed include single-reed instruments in Egyptian antiquity and from the 10th through the 17th centuries; the mock trumpet; chalumeaux during the 17th and 18th centuries; Jacob Denner’s chalumeaux and clarinets; an organ pipe that sounds like a chalumeau; chalumeau players; chalumeau descriptions from the mid-18th century; later documented chalumeau makers; chalumeau reproductions; how and why Johann Christoph Denner improved the chalumeau and invented the clarinet, based on previous studies of mechanical inventions; chalumeau and clarinet music and composers; and the Baroque clarinet’s use by traveling musicians, in court and aristocratic music, church and civic music, and military music.
