A K-Band Bulk Acoustic Wave Resonator Using Periodically Poled Al0.72Sc0.28N

IEEE Electron Device Letters, 2023
This letter presents a K-band bulk acoustic wave (BAW) resonator constructed from an Al0.72Sc0.28 N periodically poled piezoelectric film. The resonators exhibited dominant resonance responses around 20 GHz, approximately four times higher than the ...

Accurate Detection of Doppler Cardiograms With a Parameterized Respiratory Filter Technique Using a K-Band Radar Sensor

IEEE transactions on microwave theory and techniques, 2023
Cardiogram is one of the most important factors for health assessment. As a new expression of cardiograms, the Doppler cardiograms (DCGs) detected remotely via Doppler radar sensor (DRS) provide rich details of the heart motion.

Broadband Circularly Polarized Magnetoelectric Dipole Antenna and Array for K-Band and Ka-Band Satellite Communications

IEEE Transactions on Antennas and Propagation, 2022
A circularly polarized (CP) magnetoelectric dipole (ME-dipole) antenna with wide impedance bandwidth and 3 dB axial ratio (AR) bandwidth is proposed. The antenna is fed by a microstrip line and coupled through a modified cross-slot on the ground plane ...

Circularly Polarized Transmitarray Antenna for CubeSat Intersatellite Links in K-Band

IEEE Antennas and Wireless Propagation Letters, 2020
A circularly polarized transmitarray antenna based on aperture-coupled patches is presented for CubeSat intersatellite-link applications in K-band. The concept of aperture coupling simplifies the design of transmitarray elements, as it omits the need for

K-band diamond MESFETs for RFIC technology

2009 IEEE Radio Frequency Integrated Circuits Symposium, 2009
Diamond is one of the suitable semi-conductor for vacuum electronics replacement in high power and high frequency applications. Sub-micron gate-length (200 nm) Metal Semiconductor Field Effect Transistor (MESFETs) have been fabricated on h-terminated polycrystalline diamond and characterized in order to investigate the possibility of RFICs integration.

High-K band structures in 164Er

Zeitschrift für Physik A Hadrons and Nuclei, 1997
Several of the known rotational bands in 164Er are extended considerably (to around 35 h). In addition, a new coupled band is established and found to decay by an isomeric transition with t1/2 ≥ 170 nsec, to the 11t - state of the known Kπ =7− two-quasi-proton band. The new band is interpreted as a four-quasi-particle structure, with measured values of
