Miniaturised self-resonant split-ring resonator antenna [PDF]
Electronics Letters, 2009 A self-resonant miniaturised antenna composed of a broadside-coupled split ring resonator (SRR) and an excitation arc-shaped monopole is presented. The size of the antenna and its resonance frequency is essentially defined by the SRR dimensions and geometry, while the input resistance at the resonance is governed by the arc length of the monopole ...

Enhancement of second harmonic generation in a doubly resonant metamaterial [PDF]
Applied Physics Letters 99, 024101 (2011), 2011 We investigate second harmonic (SH) generation in a doubly resonant metamaterial. We show that SH generation can be enhanced when the resonant condition is satisfied for the SH frequency as well as for the fundamental frequency. A unit cell of the doubly resonant metamaterial consists of two coupled resonators, one of which resonates at the fundamental

On the Radiation Properties of Split-Ring Resonators (SRRs) at the Second Resonance [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2015 The radiation properties of split-ring resonators (SRRs) at their second resonance frequency are studied for the first time in this work. In particular, the electric and magnetic dipole moments of the edge-coupled SRR are calculated analytically under the assumption of strong coupling between the internal and external rings. Based on these results, the

Efficient second harmonic generation in a metamaterial with two resonant modes coupled through two varactor diodes [PDF]
Applied Physics Letters, Vol. 100, pp. 044103 (2012), 2012 We present an effective method to generate second harmonic (SH) waves using nonlinear metamaterial composed of coupled split ring resonators (CSRRs) with varactor (variable capacitance) diodes. The CSRR structure has two resonant modes: a symmetric mode that resonates at the fundamental frequency and an anti-symmetric mode that resonates at the SH ...

Experimental and numerical analyses of the resonances of split ring resonators [PDF]
physica status solidi (b), 2007 AbstractThe authors investigate the resonances of split‐ring resonator (SRR) structures experimentally and theoretically. The transmission measurements were performed on a single SRR unit cell and periodic arrays of SRRs. The magnetic response of the SRR structure was demonstrated by comparing the SRRs' transmission spectra of with that of closed ring ...

Controlling split-ring resonators with light [PDF]
Applied Physics Letters, 2011 We propose an original approach for creating tunable electromagnetic metamaterials. We demonstrate experimentally that magnetic resonance of a split-ring resonator (“meta-atom” of a composite material) with a photodiode operated in photovoltaic mode can be tuned by changing the intensity of an external light source. Moreover, for two coupled resonators,
