Bandpass filter-integrated multiwavelength achromatic Metalens
Photonics Research, 2021The design of large-scale, high-numerical-aperture, and broadband achromatism is a big challenge in metalens research. In fact, many colorful imaging systems have RGB color filters, which means the achromatism only for RGB lights would be sufficient ...

IPD-Based Miniaturized Wideband Bandpass Filter With Frequency-Dependent Complex Source and Load
IEEE Transactions on Plasma Science, 2021In this article, an ultraminiaturized bandpass-filtering matching network based on GaAs substrate integrated passive device (IPD) technology is proposed, which is suitable for frequency-dependent complex source and load.

Supercompact and Ultrawideband Surface Plasmonic Bandpass Filter
IEEE transactions on microwave theory and techniques, 2020We propose a supercompact and ultrawideband (UWB) bandpass filter for spoof surface plasmonic polariton (SSPP) mode. By using meander-line technology, the electrical size of the proposed SSPP structure is reduced dramatically, which is only about 1/4 of ...

Quasi-Reflectionless Microstrip Bandpass Filters Using Bandstop Filter for Out-of-Band Improvement
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2020In this brief, a class of microstrip bandpass filters (BPFs) with quasi-reflectionless behavior on both input and output ports is presented. A single-port reflectionless BPF is proposed by shunt connecting one bandstop filter cell namely one-cell.

Design of a very compact and sharp bandpass diplexer with bended lines for GSM and LTE applications
AEU - International Journal of Electronics and Communications, 2019In this paper a new miniaturized bandpass-bandpass diplexer with sharp pass-band is designed and fabricated. The proposed diplexer includes two bandpass filters with sharp pass-bands.

In image analysis and image coding there have been an increased use of multiresolution images, called pyramids or quad trees. In a recent paper Burt and Adelson [2] achieved good results with a Laplacian (bandpass) pyramid to compress image data. One problem with the conventional approach is that too many dimensions (samples) are used to describe the ...

The behavior of orthogonal frequency division multiplexing (OFDM) signals in bandpass nonlinearity is presented. In particular, in-band bit-error-rate (BER) degradation and induced adjacent channel interference, as a result of amplitude limiting or clipping, are analyzed.
