I guess I'll bite since they are asking 2 years ahead of time rather than 2 weeks ahead of time, and they are asking about fields of engineering rather than a straight-out project which I guess is a bit confusing sometimes especially if you just entered electrical in 2nd year.
Some fields in electronics (and electrical):
-microelectronics (like microprocessors, VLSI)
-power electronics (motor drivers, power supplies, power generation and distribution)
-communications (overlaps with RF circuits but also includes wire-wire in addition to wireless, audio, video, radio, TV, data compression, signal transmission)
-digital electroncs (digital filters, and other stuff which overlaps with microelectronics, signal processing)
-analog electronics (filters, RF, mixes in with every other field, especially RF)
-control systems (motor control, making a system approach a desired state as fast as possible without overshooting)
-robotics (overlaps with control systems and can also overlap with analog digital, and many other fields )
- Electronic Materials & Nanotechnology (integration of semi-conductors and nanoscale sensors)
These are not strictly separate or clear-cut fields since every field overlaps with every other field.
