Microwave Heating Consulting

SiberSci, LLC provides Microwave Heating Consulting resources for both continuous flow and batch processing of dielectric materials that include solids, films, powders, and liquids.  SiberSci, LLC provides services for the theoretical analysis, design, development, fabrication, testing, validation, and optimization of microwave heating systems for laboratory and industrial applications.  Our experience allows us to review the pertinent material properties, client defined temperature specifications for a defined volume and mass of dielectric material, time constraints for heating the defined volume and mass of dielectric material, from which SiberSci can make recommendations for one or more microwave hardware configurations to satisfy these requirements.  SiberSci is one of the few consulting and contract services available with expertise using:

  1. Vacuum Electronic Device (VED) amplifiers and oscillators:
    1. Magnetrons
    2. Klystrons
    3. TWTs
    4. Fast-Wave Devices (gyrotrons)
  2. Solid-State amplifiers and oscillators:
    1. LDMOS
    2. GaN
    3. SiC
  3. Transmission Line, Resonator, and Spatial Power Combining of multiple VED and solid-state sources.
  4. Microwave heating applicators:
    1. Cylindrical resonators operating in fundamental or higher order mode(s).
    2. Rectangular resonators operating in fundamental or higher order mode(s).
    3. Clam-shell resonators operating in fundamental or higher order mode(s).
    4. Over-moded microwave oven cavities.
  5. Temperature measurements inside resonators using Optical Thermocouples and IR Cameras.
  6. Measurement of frequency and temperature dependent material properties (conductivity, permittivity, permeability, thermal conductivity, thermal diffusivity, density, specific heat,…) of materials to be heated in a microwave resonator to optimize heating process and quality of product.

 SiberSci can also review proprietary material specifications for these efforts using a Non-Disclosure Agreement (NDA) to protect the client’s business sensitive, Intellectual Property (IP), or Proprietary Data (PD) for this material.  Performance and physical limitations for microwave heating concepts will be documented during the review process, and modifications to the concepts will be documented to illustrate how the concepts must be adapted to satisfy the client requirements for their dielectric material.  If some portion of the client defined performance specification is found to be physically impossible to achieve, then these problem areas will be revealed along with recommendations to circumvent these barriers for achieving the requisite performance.

SiberSci, LLC is experienced using Ansys HFSS with Ansys Multiphysics, or Comsol MultiPhysics to support the Computational ElectroMagnetics (CEM) aspects of these programs for temperature dependent simulations of dielectric materials.  Clients can specify use of one or more of these CEM tools for their project as long as the client provides a valid license for using the code, or pays for contract access to the code of choice.  If the client is unable to select the appropriate CEM code for their project, then SiberSci is prepared to assist each client with selecting the appropriate CEM codes(s) to ensure the success of their project. 

It is important for each client to realize that the accuracy of CEM simulations are dependent upon the frequency and temperature dependent material properties (conductivity, permittivity, permeability, thermal conductivity, thermal diffusivity, density, specific heat,…) of the metals and dielectrics used for fabricating their circuits, so these material properties must be measured so they can be included in the CEM simulations.  Laboratory and contract resources are available to determine these material properties, which are essential for providing accurate CEM simulations of circuits and systems.  SiberSci can provide each client with the capability to only use valid material properties for their CEM simulations.

In conclusion, please submit your inquiry for a Microwave Heating Consulting project to Dr. Scott Best, and specifically state if a Non-Disclosure Agreement (NDA) is required to protect business sensitive information, Intellectual Property (IP) or Proprietary Data (PD).   SiberSci will provide a NDA for review, negotiation, and amendment by the client to safeguard and protect their IP and PD.  SiberSci will also provide a budgetary quotation and schedule for performing the client defined Microwave Heating Consulting effort after reviewing the performance and size requirements.  Work on the Microwave Heating Consulting project will commence when a contract has been negotiated and legally executed by SiberSci and the client.
