Various Links Applied Computational Electromagnetics Society (ACES) Online VK1BRH page, antenna simulation - some interesting info, an article on sloping dipoles for instance. - Univ of Surrey professor David Jefferies's great site with some good theory and explanations in practical terms. - Professor Georgieva's site - look at the lecture notes from previous courses.. recommended by Prof. Jeffries, above. - Steven Castillo's page for NMSU EE315, Transmission Line Analysis, has most of the usual equations. - electromagnetics library at JPL, mostly commented links to other stuff - K.E. Schmidt ( Simplified Mutual Impedance of Nonplanar Skew Dipoles - I was using this as a basis for computing mutual Z, before I decided to bite the bullet and just fire off NEC to do the calculations each time.
