Compact Substrate Integrated Waveguide Multiband Band Pass Filter using Octagonal Complementary Split Ring Resonators

Transmission line structure based on substrate integrated waveguide (SIW) loaded with new structure of octagonal complementary split ring resonator (CSRR) has been proposed. The SIW loaded CSRR pair is used in dual/quad octagonal structure to design dual band pass filter (single and double pole) with improved performance characteristics. The proposed band pass filter (BPF) yields two passbands ...

Substrate Integrated Waveguide Filters with Broadside-Coupled Complementary Split Ring Resonators

Four designs of substrate integrated waveguide (SIW) filter employing integrated broadside-coupled complementary split-ring resonators (BC-CSRR) are compared. By changing the orientation rings, four types of SIW unit cell are proposed and investigated and it is shown that, for one particular topology, two poles and two zeroes can be realised with a single unit cell. Bandpass filters based on th...

A Compact Ultra-Wideband Bandpass Filter with Sharp-Rejection using Complementary Split Ring Resonators

A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...

Highly tunable hybrid metamaterials employing split-ring resonators strongly coupled to graphene surface plasmons

Metamaterials and plasmonics are powerful tools for unconventional manipulation and harnessing of light. Metamaterials can be engineered to possess intriguing properties lacking in natural materials, such as negative refractive index. Plasmonics offers capabilities of confining light in subwavelength dimensions and enhancing light-matter interactions. Recently, the technological potential of gr...
