a the wave amplitude of each frequency component in metres, k 1 and k 2 the wave number of each wave component, in radians per metre, and; ω 1 and ω 2 the angular frequency of each wave component, in radians per second. Both ω 1 and k 1, as well as ω 2 and k 2, have to satisfy the dispersion relation:
The propagation constant of a sinusoidal electromagnetic wave is a measure of the change undergone by the amplitude and phase of the wave as it propagates in a given direction. The quantity being measured can be the voltage , the current in a circuit , or a field vector such as electric field strength or flux density .
Flutterwave was founded in 2016 by Iyinoluwa Aboyeji, Olugbenga Agboola, and Adeleke Adekoya and is headquartered in San Francisco, California with current operations in the U.S., Canada, Nigeria, Kenya, Uganda, Ghana, South Africa, and 29 other African countries. [2] [3] [4] In 2021, Flutterwave raised a US$170 million Series C funding round. [5]
Flutterwave received one of Nigeria’s most coveted payments licenses from its central bank, signaling its status as a valuable player in the financial services sector despite recent challenges ...
New Nigerian Cinema or New Nigerian Cinema era (also known as New Wave [1] [2] or controversially as New Nollywood [3] [4]) is an emerging phase in Nigerian cinema, in which there became a major shift in the method of film production, from the video format, which came about during the video boom, back to the cinema method, which constituted the films produced in the Golden era of Nigerian ...
Experimental image of surface acoustic waves on a crystal of tellurium oxide [1]. A surface acoustic wave (SAW) is an acoustic wave traveling along the surface of a material exhibiting elasticity, with an amplitude that typically decays exponentially with depth into the material, such that they are confined to a depth of about one wavelength.
Line of sight (LoS) propagation from an antenna. Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves can only travel in a direct visual path from the source to the receiver without obstacles. [1]
Fourier optics begins with the homogeneous, scalar wave equation (valid in source-free regions): (,) = where is the speed of light and u(r,t) is a real-valued Cartesian component of an electromagnetic wave propagating through a free space (e.g., u(r, t) = E i (r, t) for i = x, y, or z where E i is the i-axis component of an electric field E in the Cartesian coordinate system).
