Transformation Optics and Transformation Electromagnetics: Comprehensive Review with Experimental Validation, Performance Analysis and Commercial Viability Assessment

The article presented here gives a detailed overview of Transformation Optics and Transformation Electromagnetics, and highlights the crucial gaps identified through a fine literature review. It includes proper experimental validation data that shows antenna gains of 15.7 to 16.1 dBi, beam steering capabilities up to ±50°, and cloaking performance with Radar Cross Section (RCS) decreasing from -9.4 dB to -9.2 dB. The article also provides quantitative standards, detailed case studies of successful implementations, a thorough analysis of limitations, as well as an economic forecast projecting a $20.9B market by 2035. The article also proposes an organized research roadmap that addresses manufacturing challenges, standardization requirements, and regulatory-related issues. This research work links theoretical concepts with real-world applications that offer the required essential guidance to researchers, engineers, and industry stakeholders in the Electromagnetics area.
