This appears to have been due to the fact that Yagi based his work on Uda's pre-announcement [5] and developed the principle of the absorption phenomenon Yagi had announced earlier. [8] Yagi filed a patent application in Japan on the new idea, without Uda's name in it, and later transferred the patent to the Marconi Company in the UK. [9]
Several performance factors, including received power, scale in proportion to the loop's area. For a given loop area, the length of the conductor (and thus its net loss resistance) is minimized if the perimeter is circular, making a circle the optimal shape for small loops. Small receiving loops are typically used below 14 MHz, where human-made ...
The whole assembly is then wrapped around the straight conductor whose current is to be measured. There is no metal (iron) core. There is no metal (iron) core. The winding density, the diameter of the coil and the rigidity of the winding are critical for preserving immunity to external fields and low sensitivity to the positioning of the ...
The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound recording technology that was popular [2] from the mid-1960s until the late 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music. [3] [4] [5]
Prestressed concrete is a highly versatile construction material as a result of it being an almost ideal combination of its two main constituents: high-strength steel, pre-stretched to allow its full strength to be easily realised; and modern concrete, pre-compressed to minimise cracking under tensile forces.
Loop-gap resonators have been used to make precise measurements of the electrodynamic properties of unconventional superconductors. [19] Most notably, a LGR was used to reveal the linear temperature dependence of the magnetic penetration depth , characteristic of a d-wave superconductor, in a single crystal of YBa 2 Cu 3 O 6.95 .
