Transition metal carbides are promising candidates for thermal protection materials due to their high melting points and excellent mechanical properties. However, the relatively conductivity is still a major obstacle its application in an ultra-high-temperature insulation system. In this work, low of dense (TiZrHfVNbTa)Cx (x = 0.6–1) high-entropy has been realized by ad...

This paper presents a quasi-elliptic filter (QEF) with arbitrary termination impedances (ATI). The proposed QEF is designed by adding cross-coupling between the first and last resonators of an ATI bandpass (BPF) Chebyshev response. QEFs can be in even-order location pair transmission zeros (TZs) controllable. To prove validity design, fourth-order were implemented on single-layer substrate-inte...

Abstract Ground-based spectroscopy of Ganymede’s surface has revealed the surprising presence dense-phase molecular oxygen (O 2 ) via weak absorptions at visible wavelengths. To date, state and stability this O temperatures pressures are not understood. Its spatial distribution in relation to albedo, expected temperatures, particle irradiation patterns, or composition may provide clues these un...
