Abstract:
Gigahertz transverse electromagnetic (GTEM) cells
are used extensively in industry for testing the impact of defined
E-fields on devices sensitive to electromagnetic interference.
Compared to anechoic chambers, GTEM cells are small,
inexpensive and require less powerful amplifiers to achieve the
same field strength. This paper presents the design, simulation
and qualification of a compact GTEM cell capable of generating
field strengths in excess of 600 V/m over a 20 × 20 × 15 cm test
cavity, whilst being less than 2.2 × 1.3 × 1 m in total size. Specific
hybrid FEM-MLFMM simulation strategies are provided to
examine high power device characteristics prior to
manufacturing, including accurate modelling of absorber
materials. Practical notes on manufacturing and qualification are
also presented.
