What exactly is radio

*"Richard Harrison" ... "Sz Bialek wrote: "Why the dipoles exhibit the directional pattern?". John D. Ktaus wrote on page 3 of his 1950 efition of "Antennas": Fig. 1-3. a length chart for EM waves from the microscopic to the astronomic.. Kraus was a famous radio astromoner. He obviously believed the EM Spectrum *was continuous, so do I. Terman begins his antenna section in his 1955 edition of "Electronic and Radio Engineering" on page 864. He explains and illustrates how vectors form and control the far field radiation pattern of antennas. Polarization is the direction of the electric field in the antenna and in the field produced by the antenna. Electric field is along the wire. If antenna has the ball on the end the electric field is at right angle to tha ball surface. Dipoles have nulls at their ends and maxima perpendicular to the conductor as Terman shows in Fig. 23 on page 865, At the ends of the dipole the voltage is doubled (at least). Today, the postman felivered my eagerly awaited copy of W2DU`s "Reflections III" and I can`t wait to read it either. In meantime read this:http://en.wikipedia.org/wiki/Standing_wave In Maxwell's hypothesis the electricity is incompressible. Standing waves in antennas are the experimental prove that the hypothesis is erroneous. See what Maxwell wrote: "I propose now to examine magnetic phenomena from a mecha nical point of view, and to determine what tensions in, or motions of, a medium are capable of producing the mechanical pheno mena observed. If, by the same hypothesis, we can connect the phenomena of magnetic attraction with electromagnetic phe nomena and with those of induced currents, we shall have found a theory which, if not true, can only be proved to be erroneous by experiments which will greatly enlarge our knowledge of this part of physics. " From:http://en.wikisource.org/wiki/On_Phy...Lines_of_Force In textbooks are prsented all theories and hipothesis. It is your choose which one do you prefer: EM, photons or like sound. S* mr. b. you and art should get together. i'm sure his vortices off the ends of his over optimized dipole would work well with your sound model of electromagnetics. he has forced the particles off the dipole by making it superconductive so they should respond like perfectly compressible sound carriers and since they are massless the sound will travel at the speed of light. how perfect could that be! both new theories come together in one big never ending thread where we can all read the bafflegab and have a big laugh behind your backs, or maybe right in your faces. Sorry i've been a bit slow responding, i had a nice trip to dayton, but didn't find any of the unwin antennas for sale, or any sound driven dipoles out in the flea market either... well, maybe next year, i'm sure you'll both be selling those new superconductive longitudinal wave generating magical levitating diamagnetic neutrino hyperwave antennas at bargain basement prices after everyone learns how bad they really are. |
