atlc's Frequently asked questions

  1. What is atlc?
  2. Formulas for transmission line properties can be found in any decent book, so why would I want to use atlc?
  3. When would using atlc not be a good idea?
  4. Can atlc calculate the loss of a transmission line?
  5. What are the hardware and software requirements for using atlc?
  6. Who wrote atlc?
  7. Under what license conditions is atlc released?
  8. Where can I download the latest version of atlc?
  9. How do I build atlc?
  10. Can atlc calculate the impedance of any transmission line?
  11. I wish to find the impedance of a microstrip line, on a printed circuit board, which is enclosed in a box. Can atlc calculate the impedance of such a transmission line, with the two dielectrics - vacuum and the fibreglass PCB.
  12. Is it possible to calculate the properties of two coupled transmission lines, which form a directional coupler, with a view to calculate the properties of a directional coupler?
  13. Given one can determine the odd and even mode impedances of a directional coupler, is it possible to perform the reverse and find the required impedances for a directional coupler of a reqired specification?
  14. How accurate is atlc?
  15. How does one enter the transmission lines structure into atlc?
  16. Does atlc need to know the dimensions of transmission lines?
  17. Bitmap files are large, can I use JPEG instead?
  18. I want to try a number of different transmission lines, all with rectangular cross sections. Drawing them as bitmaps is a bit tedious. Is there a simpler way?
  19. I ran create_bmp_for_rect_in_rect with the -v option, so that it produced some extra information to stderr. create_bmp_for_rect_in_rect indicated that it would create a grid of 615 x 201, yet the bitmap was larger at 625 x 211 pixels. Why is this ?
  20. What are the 12 programs, that form the atlc package?
