Shielding Effectiveness of a PC Case Using Three-Axis Electro-optic Sensors
نویسندگان
چکیده
This paper presents a measurement method for the shielding effectiveness (SE) of personal computer (PC) case using three-axis electrooptic sensors and vector network analyzer (VNA). The SE is obtained by taking difference between logarithmic values ratios transmitted power to input conditions with without PC case. measurements versus incident angle polarization electromagnetic fields are performed in fully anechoic chamber (FAC) frequency range 1 GHz 4 GHz. A simulation conducted compare experimental numerical results. Additionally, we measured reverberation (RC). three axes FAC RC within dB. results show that this technique, electro-optic VNA, useful both RC.

A Three-Axis Electro-Optic Probe for Specific Absorption Rate Measurement
This paper presents a new Specific Absorption Rate (SAR) measurement technique that employs the ElectroOptic (EO) probe. Conventionally, the electric field (E-field) probe comprising diode-loaded dipole sensors is employed for SAR measurements. We developed a prototype of a three-axis EO probe for SAR measurement. This three-axis EO probe is capable of measuring both the amplitude and phase of ...
متن کاملShielding Effectiveness of a Lossy Metallic Enclosure
In this paper, shielding effectiveness (SE) of a perforated enclosure with imperfectly conducting walls is evaluated. To this end, first, an accurate numerical technique based on method of Moments (MoM) ispresented. In this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. Then, the impedance boundary condition on the imperfectly conductin...
متن کاملShielding Effectiveness Simulation of Small Perforated Shielding Enclosures Using FEM
Numerical simulation of shielding effectiveness (SE) of a perforated shielding enclosure is carried out, using the finite element method (FEM). Possibilities of model definitions and differences between 2D and 3D models are discussed. An important part of any simulation is verification of the model results—here the simulation result are verified in terms of convergence of the model in dependenc...
