IONIZATION POINTThe potential required to ionize the gas of a gas-filled tube. Sometimes called firing potential [6]. |
IONIZETo make an atom or molecule of an element lose an electron, as by X-ray bombardment, and thus be converted into a positive ion. The free electron may attach itself to a neutral atom or molecule to form a negative ion [1]. |
IONOSPHEREThe most important region of the atmosphere extending from 31 miles to 250 miles above sea level. Contains four cloud-like layers that affect radio waves [10]. |
IONOSPHERIC STORMSDisturbances in the earth's magnetic field that make communications practical only at lower frequencies [10]. |
IRISA metal plate with an opening through which electromagnetic waves may pass. Used as an impedance-matching device in waveguides [11]. |
ISOLATIONThe prevention of unwanted interaction or leakage between components [14]. |
ISOMETRIC DIAGRAMA diagram showing the outline of a ship, aircraft, or equipment and the location of equipment and cable runs [4]. |
ISOTROPIC RADIATIONThe radiation of energy equally in all directions [10]. |
