چکیده
Split-ring resonators are excellent left-handed metamaterials for significant electromagnetic coupling behavior. In this work, a split-ring resonator prepared with Ni-doped zeolitic imidazolate framework-67/epoxy resin (ZIF-67/ER) was embedded in the top layer to optimize microwave absorption efficiency 2–4 GHz frequency band. The ZIF-67/epoxy served as bottom improve 4–8 Honeycomb conductive carbon black coating middle generate loss overall Based on composite structure integration technology, RL < −10 dB realized under oblique incidence of 0–70 degrees. Both simulation and experiments indicate that made lossy material can be an effective strategy broaden bandwidth increase corresponding structure’s insensitivity polarization angle microwave.

Broadband compact microstrip patch antenna design loaded by multiple split ring resonator superstrate and substrate
We present microstrip patch antenna loaded with multiple split ring resonator substrate and superstrate. We analyze how the loading of split ring resonator superstrate and substrate can improve the bandwidth compared to the simple microstrip patch antenna and microstrip patch antenna loaded with split ring resonator superstrate. Another important observation is made for multiple split ring reso...
متن کاملComplementary Split-Ring Resonator-Loaded Microfluidic Ethanol Chemical Sensor
In this paper, a complementary split-ring resonator (CSRR)-loaded patch is proposed as a microfluidic ethanol chemical sensor. The primary objective of this chemical sensor is to detect ethanol's concentration. First, two tightly coupled concentric CSRRs loaded on a patch are realized on a Rogers RT/Duroid 5870 substrate, and then a microfluidic channel engraved on polydimethylsiloxane (PDMS) i...

Improved Split - Ring Resonator for Microfluidic Sensing
We present a method of making low loss split-ring resonators for microfluidic sensing at microwave frequencies using silver coated copper wire. We show that a simple geometric modification and the use of square cross-section wire give greater electric field confinement in the capacitive region of the resonant sensor. We use a combination of theoretical analysis, finite element simulations and e...
