Dual-mode microstrip bandstop filters
2008 Asia-Pacific Microwave Conference, 2008 In this study, we proposed a novel bandstop filter using a square loop resonator. Dual-mode microstrip bandstop filters are designed and realized by employing two degenerate modes of a dual-mode microstrip square loop resonators. Microstrip loop resonators have been used extensively for bandpass filter applications.

Graphene-based dual-mode modulators
Optics Express, 2020 Mode-division multiplexing (MDM) has attracted broad attention as it could effectively boost up transmission capability by utilizing optical modes as a spatial dimension in optical interconnects. In such a technique, different data channels are usually modulated to the respective carriers over different spatial modes by using individual parallel ...

IEEE Transactions on Plasma Science, 2012 We propose exciting two modes concurrently inside a reltron's modulating cavity to increase the microwave power generated. From the harmonic components of the beam, we demonstrate that a multiharmonic beam has a higher peak and steeper gradient compared to a single-harmonic beam.

A Compact Broadband Planar Inverted-F Antenna with Dual-Resonant Modes
Applied Sciences, 2022 In this paper, a compact broadband planar inverted-F antenna (PIFA) with dual-resonant modes (TM1/2,2 and TM3/2,0) is proposed for 5G applications. By loading a pair of horizontal slots on the patch, the TM3/2,0 mode can be shifted downward and combined ...
