About me
Hello! I am Md. Raisul Islam Rifat. I have received my Bachelor of Science in Electrical and Electronic Engineering from Chittagong University of Engineering and Technology. I'm delighted to be a hardworking, adaptable, and curious individual who solves problems with patience and hopefulness. I enjoy learning new things, embracing different ideas, and gaining creative solutions to challenges. Regardless of whether I am a one-person show or part of a team, I am committed to bringing focus, commitment, and a willingness to take that extra step. I understand that consistent effort, openness to feedback, and the willingness to grow are the ingredients that fuel impactful outcomes — both professional and personal.
Undergraduate Journey
The four years at Chittagong University of Engineering and Technology have seen me not only developing as an Electrical and Electronic Engineering student but also as a problem solver and lifelong learner. Throughout the period from the very first day of lectures to the final-year projects, my life at CUET was filled with challenges, breakthroughs, and numerous late nights spent transforming ideas into functional solutions. I immersed myself in a wide range of topics — ranging from industrial systems and electronics to secure communication technologies — building both my technical expertise and my ability to work with others. Those years taught me the value of persistence, adaptability, and staying curious, no matter how challenging the task.
Undergraduate Thesis
I designed and emulated a double-negative THz negative refractive index metamaterial-based biosensor for cancer cell detection during my undergraduate thesis. It involved developing a novel metamaterial structure, validating its electromagnetic properties, and evaluating its ability of detecting cancer cells as a function of changes in refractive index. On the basis of CST Studio Suite, I evaluated transmission dips, surface current distributions, and sensitivity performance in designing an extremely precise sensing system. The project not only made me better understand electromagnetics and metamaterials but also improved my ability in simulation, data analysis, and hands-on application of sophisticated concepts.
Independent Research
In an independent research project, I studied quantum-assisted secure audio communication by combining E-91 Quantum Key Distribution, SHA-3 hashing, ChaCha20-Poly1305 AEAD encryption, and LSB audio steganography. The hybrid system offered both quantum-level key security and robust data concealment to be used with audio files. Implemented in Python using Qiskit, the project demonstrated how quantum concepts may be employed to enhance modern cryptographic methods. This work allowed me to blend my enthusiasm for next-generation technologies with actual security applications, pushing me to step outside conventional thinking.
Research Interest
My primary research interest lies in the intersection of quantum communication and secure information systems, with a focus on practical implementations that bridge theoretical concepts and real-world applications. I am particularly drawn to:
Secure communication systems integrating advanced cryptography with emerging technologies.
Practical applications of quantum principles to enhance data confidentiality and integrity.
Engineering solutions that bridge theoretical innovation and real-world deployment.
Scalable, future-proof architectures for next-generation communication networks.
