This paper deals with the effects of an electromagnetic interference (EMI) from an out-of-band signal impinging on a 2.4 GHz RF receiver operating in the linear regime. The injection signal is radiated in the near-field above the circuit package at a frequency of 60 GHz. Due to the nonlinear behavior of active devices, we observed a gain quenching leading to a complete inhibition of the receiver that...
A 60 GHz high-spatial resolution millimeter near-field scanning microwave microscope system is developed. Like in scanning near-field optical microscopy, it involves a modulation of the probe-sample distance. An analytical model of the near-field detection versus the minimum probe-sample distance is derived as a function of the harmonic rank used for lock-in detection. The model is validated owing...
In the framework of a near-field remote sensing imaging experiment we developed an interferometric detection scheme at the open end of the rectangular waveguide that serves as probe. To proceed with lock-in detection, the Gunn source is further switched at kHz frequencies. This results not only in an intensity sensitive image of the sample but also in a phase-contrast image that bring complementary...
A 60 GHz high spatial resolution millimeter near-field scanning microwave microscope (NFSMM) system is developed with aim of non-destructive testing of material and circuits. Like SNOM, it involves a modulation of the probe-to-sample distance. We derive an analytical model of the probe detection versus the standoff distance and the harmonic order used for lock-in detection. Both the model and experiments...
Electromagnetic (EM) injection experiments require an accurate and quantitative knowledge of the voltage effectively coupled to a target line or circuit in order to predict disruptive behavior or sensitivity of digital IC circuits to EM threats. To answer this question we derive here a complete quantitative model of the coupling of our magnetic probe to a microstrip line. The novelty of this model...
A near-field reflectometry experiment operating at 60 GHz is built in view of material and circuit inspection. The linearly-polarized electric-field probe is a bow-tie antenna obtained from femtosecond laser cutting of pieces in a tungsten metal sheet subsequently attached to an open rectangular waveguide. First images reveal a true near-field detection with strongly subwavelength resolution up to...
