Multi-frequency measurements of the microwave sky can be decomposed into maps of distinct physical components such as the cosmic microwave background (CMB) and the Sunyaev–Zel’dovich (SZ) effect. Each of the multi–frequency measurements is a convolution of the spectrum on the sky with the bandpass of the instrument. Here we analytically calculate the contamination of the component maps that can...

The polarization sensitivity of the Joint Polar Satellite System (JPSS) J1 Visible Infrared Imaging Radiometer Suite (VIIRS) measured pre-launch using a broadband source was observed to be larger than expected for many reflective bands. Ray trace modeling predicted that the observed polarization sensitivity was the result of larger diattenuation at the edges of the focal plane filter spectral b...

Vegetation indices (VIs) are widely used in long-term measurement studies of vegetation changes, including seasonal vegetation activity and interannual vegetation-climate interactions. There is much interest in developing cross-sensor/multi-mission vegetation products that can be extended to future sensors while maintaining continuity with present and past sensors. In this study we investigated...

Filters with advanced features have numerous applications in many modern technologies. Microwave bandpass filter is one of those filters that can be used for wireless communication .This paper emphasis how to design an interdigital microwave bandpass filter for 2.45GHz. So, this paper focuses on the design of parallel coupled line bandpass filter, two sets of interdigital band-pass filter at 2....

This paper introduces a new microwave narrowband bandpass filter with a miniaturized size as well as adequate transmission and return loss characteristics for use in modern wireless communication systems. The proposed filter design topology is based on a single-mode microstrip resonators constructed in the form of Hilbert fractal geometries of the 2 and 3 iteration levels. Filter structures hav...

In this study of the precedence effect in binaural hearing, subjects adjusted the interaural delay of a wideband acoustic pointer to match the perceived intracranial position of transient test stimuli presented over headphones. The test stimuli had leading and lagging components (either brief noise bursts or clicks), each with its own interaural delay. In some test conditions, the leading and l...

Narrow bandpass filters (NBPF) are an important type of thin film filter technology that have become commonplace within the electrooptics industry. These devices are indispensable in fields such as analytical instrumentation, microscopy and telecommunications. NBPF are typically characterized as having high transmission with steep roll-offs and broad isolation. Thin film coating designs that me...

Recent developments in micromachining techniques at the University of Michigan have resulted in novel high-performance low-loss filters for microwave and millimeter-wave applications. The idea is based on suspending the filters on thin dielectric membranes to eliminate dielectric loss and dispersion problems, resulting in a pure TEM mode of propagation and conductor-loss-limited performance. Th...

Under conditions of nutrient limitation, Bacillus subtilis cells terminally differentiate into a dormant spore state. Progression to sporulation is controlled by a genetic circuit consisting of a phosphorelay embedded in multiple transcriptional feedback loops, which is used to activate the master regulator Spo0A by phosphorylation. These transcriptional regulatory interactions are "bandpass"-l...

Introduction: The new wireless and mobile communication systems use miniature Radio Frequency (RF) module design technologies to satisfy low-cost and compact size. Theses requirements are critical for some specific application such as bandpass filter, diplexer, and coupler to reduce the cost and size of mobile system. Recent advances in integration technology and device performance paved the wa...
