دانلود کتاب Basic NEC with Broadcast Applications

Basic NEC with Broadcast Applications addresses computer modeling of MF directional broadcast antennas and illustrates the assets and liabilities of the Numerical Electromagnetic Code (NEC). The book's "how to" approach reveals the fundamentals of NEC operation, teaches broadcast applications and shows the reader how to use NEC-2 to: model non-radiating networks, verify calculations, detune unused towers, design top-loaded and skirted antennas, minimize coding by moving and duplicating structures, and much more! Complete with CD, the book is an invaluable toolkit with software necessary for the design and analysis of broadcast antenna arrays.*Learn to use the method of moments computer programs to design and analyze MF directional antennas*CD includes a modified version of NEC-2, programs for geometry viewing and pattern plotting, as well as author-written post processing programs to convert target field ratios to base drive voltages and to verify the integrity of the NEC-2 analysis*Concepts taught in this book apply to analysis generated by NEC-2, NEC-4, MININEC and other method of moments computer programs"
