Measuring microwave material dielectric properties since 1996.
What We Do
MPN measures microwave material dielectric properties
- from 50 MHz to 3000 MHz
- under process conditions
- to your desired temperature ( up to 1400°C )
- in your choice of gas atmosphere
What clients say
I think the type of service and responses after the test from you is one of the best I have ever experienced.
Microwave Properties North was able to quickly and accurately measure the microwave properties of our materials, confirming the characteristics for a new process that we were looking for. This allowed us to move forward to bring a new product to market.
Ron brings years of experience to microwave property measurement and is a pleasure to work with.
Our measurements can reduce your development costs by answering these crucial questions :
- Will my material heat well in a microwave field?
- What is the best choice of frequency for heating/processing my material?
- What type and geometry of applicator is best suited to processing my material?
- How uniform will the heating of the work piece be at processing temperatures?
- Will its microwave absorption characteristics change during the processing?
- Will thermal runaway be a problem in my microwave processing system?
- Does my thermal insulation absorb/reflect microwave power at high temperatures?
Our services include
- Measurement of the complex dielectric constant of small samples, at frequencies between
50 MHz and 3000 MHz, up to high temperatures (-35°C to 1400°C), under specified industrial
processing conditions (pressure, cover gas, temperature, moisture content, temperature ramp
Measurement on ceramics, polymers, glasses, metal oxides, ferrites, liquids, organics, foods, fabrics, earthenware, minerals, biological samples, explosives, fuels ------
- Measurement of magnetic susceptibility (ie., complex permeability) between 900 MHz and 2800 MHz, up to high temperatures (-35°C to 1000°C) with either zero magnetic bias or perpendicular DC magnetic bias (up to 3 kGauss), done under specified processing conditions (pressure, temperature, moisture content, cover gas, temperature ramp rate, density)
- Measurements of Rf and microwave attenuation coefficients, half-power depths, and reflection coefficients ( using small samples), to assist in detailed applicator design and interpretation of radar and satellite images
- Assisting with design of continuous flow and batch process applicators for industrial Rf and microwave heating
- Scoping calculations of microwave heating rates and heating distributions for process simulation, including time dependent and thermal runaway effects - used for microwave process feasibility studies
