Three typical and recent GATE problems are identified for video solutions. These problems are of years 2014, 2015 & 2016. Many basic underlying concepts will emerge out which will be helpful in solving any new problem. These points are highlighted during the video solution.

First problem is of GATE 2014  . This problem is based on TE modes of rectangular waveguide.

Second problem is of GATE 2015. Longitudinal component of magnetic field inside the waveguide is given and  one has to find mode of propagation.

Third problem is of GATE 2016 . Rectangular waveguide is given, one has to determine cutoff frequencies of various TE modes and how they are arranged in increasing order of frequencies.
