TL;DR: In this article, a triple-mode hexagonal bandpass fllter with capacitive loading stubs is introduced, which adds an open capacitive stub to enlarge the equivalent self capacitance of the resonator, which declines its resonant frequencies.
Abstract: A novel triple-mode hexagonal bandpass fllter with capacitive loading stubs is introduced in this article. The technique, adding an open capacitive stub, is applied to enlarge the equivalent self- capacitance of the resonator, which declines its resonant frequencies. Three radial-line stubs in the center of top layer are used to implement this technique. One mode resonant frequency is varied with the radii of three radial-line stubs, while the other two modes are nearly not afiected. This fllter has a pair of transmission zeros which are close to the passband, thus it behaves with high selectivity. For method validation, a bandpass fllter operating at 2.4GHz is fabricated and measured. The experimental results are demonstrated and discussed.

TL;DR: In this article, the couplings join to form the connector, while the stub tubes telescopically mate to provide fluid communication through the connector and the housings, and the stopper seals the stub tube while the cap matches with the housing to isolate the sealed stub tube in a spaced enclosure.
Abstract: A tubing connector having two couplings, each coupling including a central stub tube and a spaced, concentric housing. Each coupling is adapted to be placed on a tubing end with each stub tube in fluid communication therewith. The couplings join to form the connector while the stub tubes telescopically mate to provide fluid communication through the connector and the housings telescopically mate to isolate the mated stub tubes in a spaced enclosure. Each coupling is provided with a closure which includes a cap and a stopper. The stopper seals the stub tube while the cap telescopically mates with the housing to isolate the sealed stub tube in a spaced enclosure. The closures are dimensionally configurated to mate while the couplings are mated to form the connector.

TL;DR: In this article, a simplified composite right/left-handed transmission line (CRLH) structure without the series capacitance or the shunt inductance was developed using microwave components with nonlinear phase responses.
Abstract: Microwave components with nonlinear phase responses are developed using a simplified composite right/left-handed (CRLH) transmission-line (TL) structure without the series capacitance or the shunt inductance. Using such a simplified CRLH structure, arbitrarily dual-band microstrip components have been realized in compact sizes such as a quarter-wavelength short-circuited stub and dual- band branch-line couplers. Simulation and measurement results are given to demonstrate the efficiency and good performance of the proposed components. For the quarter- wavelength short-circuited stub based on the simplified CRLH-TL structure without the series capacitance, it has been shown that the insertion loss is less than -0.1dB. For the arbitrarily dual-band branch-line coupler, experiment results exhibit that S/sub 21/ and S/sub 31/ are larger than -3.6dB, the isolations are smaller than -30dB, the return losses are smaller than -20dB, and the phase differences are within 90/spl deg//spl plusmn/1.8/spl deg/.

TL;DR: In this paper, a coupled plasmonic waveguide resonator system which can produce sharp and asymmetric Fano resonances was proposed and analyzed, and the potential of the proposed Fano system as an integrated slow-light device and refractive index sensor was investigated.
Abstract: A coupled plasmonic waveguide resonator system which can produce sharp and asymmetric Fano resonances was proposed and analyzed Two Fano resonances are induced by the interactions between the narrow discrete whispering gallery modes in a plasmonic square cavity resonator and the broad spectrum of the metal–insulator–metal stub resonator The relative peak amplitudes between the 1st and 2nd order Fano resonances can be adjusted by changing the structure parameters, such as the square cavity size, the stub size and the center-to-center distance between the square cavity and the stub resonators And the 1st order Fano resonant peak, which is a standing-wave mode, will split into two resonant peaks (one standing-wave mode and one traveling-wave mode) when it couples with the 2nd Fano resonance Also, the potential of the proposed Fano system as an integrated slow-light device and refractive index sensor was investigated The results show that a maximum group index of about 100 can be realized, and a linear refractive index sensitivity of 938 nm/RIU with a figure of merit of about 135 × 104 can be obtained

TL;DR: It is shown that light can be coupled efficiently from a conventional MDM waveguide to the plasmonic waveguide system, which supports a subwavelength broadband slow-light guided mode with a tunable slowdown factor at a given wavelength.
Abstract: We introduce a plasmonic waveguide system, which supports a subwavelength broadband slow-light guided mode with a tunable slowdown factor at a given wavelength. The system consists of a metal-dielectric-metal (MDM) waveguide side-coupled to a periodic array of MDM stub resonators. The slowdown factor at a given wavelength can be tuned by adjusting the geometrical parameters of the system. In addition, there is a trade-off between the slowdown factor and the propagation length of the supported optical mode. Finally, we show that light can be coupled efficiently from a conventional MDM waveguide to the plasmonic waveguide system.
