A system component used |
 A resonant cavity |
 2 - 10GHz resonant cavity |
Features
- ■ Measurement by a resonant cavity
- By inserting a sample into the resonant cavity, the electrical field changes with the dielectric properties of the sample mateiral, which in turn changes the resonant frequency and the Q factor of the cavity. The dielectric properties are then calculated from the changed resonance.
- ■ Fast and easy measurement
- The dielectric constant can be measured in a short time by inserting a sample into the resonant cavity.

- ■The general of the system
- 1. What is the resonant cavity type microwave dielectrometer ?
The resonant cavity type microwave dielectrometer is the system which measures dielectric properties at microwave frequencies. This system has 2 types, which use either a synthesized sweep oscillator (an alternative to a network analyzer) or a network analyzer.
- 2. What are the system components of the synthesized sweep oscillator type and the network analyzer type ?
The synthesized sweep oscillator type consists of an oscillator, which includes a microwave signal generator and a detector, a measurement cavity, a customized software, and accessories. This is a low cost type because it does not have expensive measurement devices. The network analyzer type sets up with your network analyzer to use. It consists of a measurement cavity, a customized software, and accessories.
- 3. What is the difference between this system and the conventional system ?
The resonant cavity type microwave dielectrometer has highly accurate measurement software. By simply inserting a material into the slot of the cavity, and following an easy step-by-step operation of the software wizard, the measurement is achieved complex dielectric properties very accurately and very simply.
(*Please see the movie titled "4.Actual Measurement" on the top page.)- 4. What is the tool to measure ?
The tool to measure is a resonant cavity which has single-frequency point per a resonator. It is suitable to measure for thin films, multilayer structure materials, ceramics, liquid, various resin and powder. The measurement method was established by JIS(Japanese Industrial Standards) C 2565.
- 5. How good is the accuracy ?
The random error of the epsilon is estimated to be less than 1%, and the error of the tangent delta is less than 5%.
- ■Materials to be tested
- 1.What are the requirements for the sample material ?
The measurement method by the resonant cavity is destructive measurement. The dimension of the sample to be tested should be larger than 80mm(L) x less than 3mm(W). Thickness is 0.05mm - 1mm.
- 2. What are the limitations of the dielectric properties ?
This system can measure relative dielectric constants from 1 to 30, and the loss tangent from 0.0001 to 0.1.
- 3. Is it possible to try sample measurements ?
Yes. Please send your sample materials. We will send you the measurement results.
