It may limit your job opportunities in certain industries or roles, but there are still plenty of opportunities for EE graduates without a background in communications or electromagnetics. Many companies value a diverse skill set and are willing to train employees in specific areas.
Yes, success as an EE is not solely dependent on knowledge in communications or electromagnetics. There are many other aspects of electrical engineering, such as circuit design, power systems, and control systems, that you can specialize in and be successful in your career.
It may affect your understanding of certain concepts that are directly related to communications or electromagnetics, but overall, the fundamentals of electrical engineering are interconnected and you can still develop a strong foundation in other areas.
Yes, there are many online resources, books, and tutorials available that can help you learn about communications and electromagnetics. You can also consider taking continuing education courses or attending workshops and conferences to expand your knowledge in these areas.
It may limit your options for specific research topics or programs, but it is not a determining factor for pursuing a graduate degree in electrical engineering. Admissions committees look at a variety of factors, including your overall academic performance and potential for research. Additionally, you can always take additional courses or conduct independent study to gain knowledge in these areas before applying to graduate school.
