Research, Development and Consultancy
• Survey of actual radiation hazards and prediction radiation levels.
• Advice on narrow and ultra-broad-band microwave antennas
• Materials Analysis and Measurement. (Microwave windows,
radomes and structural components etc)
• Depth Measurement (The measurement of depth within containers of
corrosive liquids, grain etc)
• Moisture Content. (Measuring on-line moisture content of various
commercial products, such as soap).
Frequency Selective Surfaces (FSS) for defence and civil
applications
• Design of antennas, metamaterials, radomes and radar
absorbent materials
• FSS consultancy and custom FSS products
• Q-par Dichroic Array Software ; analysis of transmission,
reflection and grating lobe properties of composite
structures including FSS
