A few things to know before working with the µSYC group

If you are a student/project researcher/doctoral scholar who is working/planning to work with the µSYC group , here are a few things to note:
  1. I prefer reports, papers, and presentations made in LaTeX (read LateK). Please familiarize yourself with this tool at the earliest. It will be immensely helpful at later stages as well.
  2. Learn the use of XCIRCUIT. This is a wonderful, free software which lets you draw circuit diagrams, system/block diagrams, flowcharts, and more. What’s better, it is free and easily integrable with LaTeX and gives your document a professional look.
  3. Learn to use a professional graph plotting software. Several free software such as SCIDavis allows you to make professional plots for your reports and papers.
  4. Some other free tools which are a bonus to know– NGSPICE/LTSPICE (general circuit simulation), and QUCS (microwave circuits).
  5. Most of the above free software are tailor-made for Linux OS. It will be of great value if you are familiar with Linux OS (Debian- or Redhat-based).
  6. Among proprietary tools, learn the use of EAGLE, a PCB schematic and layout editor. We use it extensively.
  7. All papers, reports etc. which you would like me to peruse must be submitted (preferably in hardcopy) at least a weekend before you need them checked.

Short-term internships

Those interested in applying for a summer/winter internship with my group should do so via the centralized application portal of IIT Bhubaneswar. I shall not respond to individual emails asking for internships. Thank you for understanding.
