While they may have a dominant effect on final temperature patterns, their electromagnetic modeling has been a long recognized challenge, due to small transverse dimensions, microwave semi-transparency, and complicated shapes. This work addresses effective representation of susceptors deposited upon or buried within microwaveable food packages of non-Cartesian geometries. It focuses on packages shaped as cylinders or truncated cones, which are non-trivial to be described on a Cartesian mesh, but more easy to define in a cylindrical system. Borrowing from previous experience with soft and hard antenna surfaces, an idea of simplifying the susceptor structure is proposed. Two specific models are implemented in the FDTD environment and validated. Computational examples prove a significant reduction in RAM and CPU requirements, within a permissible accuracy margin. Conclusions apply to potential use of the new models for microwave heating simulations, but also emphasis synergy effects between various microwave technologies.","PeriodicalId":425104,"journal":{"name":"2012 19th International Conference on Microwaves, Radar & Wireless Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123076121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed wireless power transmission system consists of the 130W class-F power transmitter, two magnetic resonance couplers and 30W full bridge diode rectifier receiver. The transmitter is composed of DDS(Direct Digital Synthesizer) block, class-F power amplifier and communication block to implement the frequency searching and power control function. Two magnetic resonance couplers are designed with a small spiral resonator. The diameter size of the spiral coil is 30cm(1.8 λ /1000). The receiver is composed of full bridge diode rectifier, overvoltage protection (OVP) with active dummy load, DC to DC converter and communication block. For the power control scheme, a communication block is embedded in the transmitter and the receiver. Using the communication block, the message about the error value of the received power is sent by the receiver to transmitter and the transmit power is controlled by transmitter using the received message. The power consumption of the fishing port is about 30W and the total power efficiency of this system is about 40%.","PeriodicalId":425104,"journal":{"name":"2012 19th International Conference on Microwaves, Radar & Wireless Communications","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133002950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For isolator with R tuning elements, based on physically measured scattering characteristics, ANNs are used as a multidimensional approximators realizing inverse models for all R sub-devices. The sub-isolators (sub-devices) are obtained by successive detuning and removing tuning screws. For each subisolator, the input and output vectors are defined as physical scattering characteristics and the corresponding positions of the tuning element, detuned, in controlled way. Throughout the tuning process, these inverse models are used for calculating the tuning element increments needed for adjusting the tuning element in the proper position. Earlier that method was successfully used in filter tuning process so it encourage authors to adopt and verify that method in other microwave devices tuning. The obtained and presented results of our investigations prove that mentioned above method may be successfully used for other devices and systems that require tuning.","PeriodicalId":425104,"journal":{"name":"2012 19th International Conference on Microwaves, Radar & Wireless Communications","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133041648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
