“…The dielectric (Pyrex) substrate of thickness h1 on which the coplanar line is micro-machined is characterized by a relative permittivity r1 and thickness h1. A good approximation of the guided wavenumber β of the fundamental mode in this coplanar waveguiding structure is solution of the following dispersion equation (see, e.g., [13,14] for details on the Transverse Resonance Method applied to planar waveguides):…”

Abstract. The development of a new passive wireless pressure sensor, based on an electromagnetic transduction approach, is reported. The sensing element is a flexible high resistivity silicon membrane located above a coplanar quarter-wavelength resonator. The comprehensive coverage of the physical bases is beyond the scope of this paper. For the remote extraction of the applied pressure value, the passive pressure sensor is connected to a broadband horn antenna via a coaxial delay line. When interrogated by a frequency modulated continuous wave radar, the level of the backscattered signal changes versus the pressure applied to the proof body. Through this interrogation principle, the sensor provides load impedance that is reflected back to the radar reader: the measured dynamic is about 0.8 dBm/Bar. This completely passive and wireless pressure telemetry micro-sensor has been designed, fabricated and characterized, thereby eliminating the need for contact, signal processing circuits, and power supplies needed by conventional active sensors.

“…The concept of virtual sources and its representation by an equivalent circuit have been proposed by H. Baudrand [20][21][22][23] as a very convenient way to derive the boundary value problem in term of an integral equation. It has been applied with success to the modelling of microwave circuits by taking into account the metallic losses (see, e.g., [24]). Define two virtual field sources e (s−1) and e …”

Abstract-The concept of Scale-Changing Network is reported for the electromagnetic modeling of complex planar structures composed of a collection of metallic patterns printed on a dielectric surface and whose size covers a large range of scale. Examples of such multi-scale structures are provided by multi-band frequency-selective surfaces, finite-size arrays of non-identical cells and fractal planar objects. Scale-Changing Networks model the electromagnetic coupling between various scale levels in the studied structure and are computed separately. The cascade of Scale-Changing Networks bridges the gap between the smallest and the highest scale levels and allows forming a monolithic (unique) electromagnetic formulation for the global electromagnetic simulation of complex planar structures. Derivation of these networks is presented and key advantages of the electromagnetic approach are reported.
