For most terrestrial wireless communications purposes, antenna directionality matters only in the azimuth, or horizontal, plane. In situ recording of functioning outer hair cells (OHCs) for investigating this hypothesis is exceptionally difficult. Addition of quinoa flour had a positive effect on the FeDa% as did broad bean flour on ZnDa%. Then it may be said that the coil has lengthened the antenna to achieve an electrical length of 2.5 meters.

Consequently the (110) planes contain equal amounts of Fe and Al distributed as interlocking rectangles. Unlike the NiAI(110) surface, which retains the (1{times}l) in-plane symmetry of the bulk, FeAl(l10) reconstructs to form an ordered, incommensurate overlayer.

This can be quite a significant effect when the antenna is within a wavelength or two of the ground. But as the antenna height is increased, the reduced power of the reflected wave (due to the inverse square law ) allows the antenna to approach its asymptotic feedpoint impedance given by theory. At lower heights, the effect on the antenna's impedance is very sensitive to the exact distance from the ground, as this affects the phase of the reflected wave relative to the currents in the antenna Smart Antennas: Adaptive download pdf download pdf.

Second one is Brillouin Optical Time Domain Analysis (BOTDA), which uses a more complicated phenomenon known as Stimulated Brillouin Scatter (SBS). The BOTDA technique is significantly more powerful as it uses enhanced Brillouin scattering through two counter-propagating beams.
