31Subwavelength-diameter optical fibre — A subwavelength diameter fibre wraps light around human hair. Subwavelength diameter optical fibre (SDF or SDOF) is an optical fibre whose diameter is less than the wavelength of the light being propagated through the fibre. An SDOF usually… …
32Cavity magnetron — Magnetron with section removed (magnet is not shown) …
33Coaxial cable — RG 59 flexible coaxial cable composed of: A: outer plastic sheath B: woven copper shield C: inner dielectric insulator D: copper core Coaxial cable, or coax, has an inner conductor surrounded by a flexible, tubular insulating layer, surrounded by …
34Negative index metamaterials — A negative index metamaterial causes light to refract, or bend, differently than in more common positive refractive index materials. Negative index metamaterials or negative index materials (NIM) are artificial structures where the refractive… …
35Cutoff frequency — This article is about signal processing. For other uses, see Cutoff (disambiguation). Magnitude transfer function of a bandpass filter with lower 3 dB cutoff frequency f1 and upper 3dB cutoff frequency f2 …
36Dispersion (optics) — This article is about dispersion of waves in optics. For other forms of dispersion, see Dispersion (disambiguation). In a prism, material dispersion (a wavelength dependent refractive index) causes different colors to refract at different angles …
37Геккер, Иван Романович — В Википедии есть статьи о других людях с такой фамилией, см. Геккер. Геккер Иван Романович нем. Johann von Hecker …
38Microstrip — Cross section of microstrip geometry. Conductor (A) is separated from ground plane (D) by dielectric substrate (C). Upper dielectric (B) is typically air. Microstrip is a type of electrical transmission line which can be fabricated using printed… …
39Double-clad fiber — Refractive index profile of dispersion compensating double clad fiber. c:core, i:inner cladding, o:outer cladding …
40Otto Julius Zobel — Born October 20, 1887(1887 10 20) Ripon, Wisconsin Died January 1970 (age 82) Morristown, New Jersey …
