Element (formerly Riot and Vector [13]) is a free and open-source software instant messaging client implementing the Matrix protocol. [ 14 ] Element supports end-to-end encryption , [ 15 ] private and public groups, sharing of files between users, voice and video calls, and other collaborative features with help of bots and widgets.
A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded ...
A graphical user interface (GUI) showing various elements: radio buttons, checkboxes, and other elements. A graphical user interface, or GUI [a], is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation.
A two-element array with the elements spaced a quarter wavelength apart has a distinct cardioid radiation pattern when the second element is driven with a source −90° out of phase relative to the first element. A log-periodic antenna (LPDA) consists of many dipole elements of decreasing length, all of which are driven. However, because they ...

Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys. [ 1 ] Engineers use Ansys HFSS primarily to design and simulate high-speed, high-frequency electronics in radar systems, communication systems, satellites, ADAS, microchips, printed circuit boards, IoT ...
The solution of the system then is as follows. Let the driven element be designated 1 so that V 1 and I 1 are the voltage and current supplied by the transmitter. The parasitic element is designated 2, and since it is shorted at its "feedpoint" we can write that V 2 = 0. Using the above relationships, then, we can solve for I 2 in terms of I 1:
