Abstract
This letter presents experimental results concerning a thin film bulk acoustic wave resonator realized on a thin GaN membrane and covered with a thin film of double walled carbon nanotube mixture. The quality factor was measured before and after the coating of the resonator with the nanotube thin film. The quality factor has increased more than ten times when the resonator was coated with nanotubes, due to their high elasticity modulus and low density, which confers a much higher acoustic impedance of the resonator electrodes and thus confines much better the longitudinal acoustic standing waves inside the resonator.

Abstract
This paper presents an analytical design methodology for 3D broadside couplers using new concept of compensation by coupled lines at both ends of a main coupler section. This compensation technique introduces a degree of freedom in the design which can enhance the compactness or the isolation of the coupler. Simulations have been performed and good agreement with the analytical analysis is observed. Two demonstrators have been then optimized and demonstrate a size reduction of 50% or a 10dB isolation improvement depending on the compensation scheme followed.

Abstract
The attenuation and the electrical permittivity of the double-walled carbon nanotubes (DWCNTs) were determined in the frequency range of 165 GHz. A micromachined coplanar waveguide transmission line supported on a Si membrane with a thickness of 1.4 µm was filled with a mixture of DWCNTs. The propagation constants were then determined from the S parameter measurements. The DWCNTs mixture behaves like a dielectric in the range of 165 GHz with moderate losses and an abrupt change of the effective permittivity that is very useful for gas sensor detection.
