The questions are:

  1. How can i make an inductor using transmission line?
  2. How can i make a capacitor using transmission line?

    Your question and your title seem to be asking two opposite questions. – Hearth Oct 14 '18 at 14:08
  • Yes i have asked two questions in one title – Mimi Mouse Oct 14 '18 at 14:17
  • @MimiMouse Is this related to [Richard's transformations](http://www.ittc.ku.edu/~jstiles/723/handouts/Richards%20Tranformation%20.pdf) and [Commensurate line circuit](https://en.wikipedia.org/wiki/Commensurate_line_circuit)? - Your question is **very** bony, some meat to the bones would make this question proper. – Harry Svensson Oct 14 '18 at 14:37
  • It's a conceptual question for job interview can any one help me to find the answer – Mimi Mouse Oct 14 '18 at 15:07

    Take a transmission line that's significantly shorter than 1/4 wavelength at the highest frequency of interest. Connect the near ends to your circuit (this works best if one end is grounded). Short the far end -- it's an inductor. Now open the far end -- it's a capacitor. Now go study so you can answer the follow-on question, which is "why?" – TimWescott Oct 14 '18 at 15:39

A short circuit terminated transmission line will look like an inductor or a capacitor at certain lengths when driven at the appropriate frequency: -

This website where I took the image also shows the result if the transmission line is open circuit here.

My answer here gives a little more insight to the math.
