This thesis presents a rigorous investigation into the electromagnetic behavior of one-dimensional periodic arrays composed of canonical resonant elements, specifically electric dipoles and magnetic loops functioning as "Meta-Guides" for surface wave propagation. The research establishes a systematic physical framework to decode how inter-element spacing and mutual coupling govern collective wave phenomena. By employing a synergistic methodology that bridges analytical modeling, Fast Fourier Transform (FFT) based numerical simulations, and experimental validation, the study reveals a fundamental duality between the electric and magnetic resonator chains. While both structures support guided modes, loop arrays demonstrate significantly higher mutual impedance due to strong near-field magnetic coupling, a regime where traditional analytical convergence often struggles compared to robust FFT techniques. A key theoretical contribution of this work is the mapping of reactive loading to physical geometry; the analysis confirms that inductive loading electromagnetically mimics an increase in element length, whereas capacitive loading effectively shortens the resonator. This insight offers a simple, powerful design rule for tuning standing waves and matching networks. Furthermore, the study distinguishes between attenuation mechanisms, highlighting a critical divergence between current amplitude decay and power transport decay in post-resonant regimes. Experimental validation conducted using a Vector Network Analyzer in the 9–10 GHz range, corroborated these theoretical models. The fabricated arrays achieved transmission enhancement when interposed between a transmitter and a receiver of up to 15 dB at resonance compared to free-space propagation and maintained this wave-guiding capability even under significant mechanical bending and induced strain. Additional proof-of-concept in energy scavenging at 2.4 GHz further underscore the practical potential of these structures. Ultimately, this research positions coupled resonator arrays as highly tunable, mechanically robust platforms essential for the next generation of wearable sensors and integrated wireless communication systems.
