"Why are your`s so special?" Art can`t answer but I will. Art is dead wrong. Radiation resistance is a resistance. Radiated energy has its current in-phase with its voltage. FCC defines output power of a transmitter as RF current at a designated common-point of known resistance, thus calculated as I squared R. Terman says on page 2 of his 1955 opus: "A plane parallel to the mutually perpendicular lines of electric and electromagnetic flux is called the wavefront." Mutually perpendicular describes the physical positions of the fields, not the timing of their waxing and waning, which is simultaneous. The intrinsic impedance of free-space is the E/H ratio, a resistance of 377 ohms. The vector product of E and H gives the Poynting vector, or power flow in watts per square neter in the direction of propagation. The above is found on page 7 of E.A. Laport`s "Radio Antenna Engineering". Art has been promulgating pure baloney no matter how it is sliced about vector analysis. I recommended B. Whitfield Griffith,Jr.`s "Radio-Electronic Transmission Fundamentals" to Art for an understanding of Maxwell and radiation. He obviously hasn`t yet studied Mr. Griffith`s work. I hate to dash the dreams of an old man, but he is leading others astray. Best regards, Richard Harrison, KB5WZI |
