A novel compact dual‐mode SIW filter with wide rejection band and selective response
Bibliographic record
Abstract
Abstract A compact dual‐mode substrate‐integrated waveguide (SIW) bandpass filter with wide upper stopband is presented. A cross shaped slot is etched on the top plane of SIW cavity to alter the second mode (TE 201 ) current distribution and move it closer to the first mode (TE 101 ), to enhance the bandwidth flatness. Removing few via near the excitation ports, provides longer path for the current to resonance and give us the transmission zeros (TZ1) in a simple way. Another 2 TZs are used to improve the stopband by suppressing higher order modes resonances. The designed filter is fabricated and tested and a very good result is achieved to confirm the design idea. There is also a good agreement between the measured and Full Wave simulated results. The fabricated sample realizes a fractional bandwidth of 9.1% at 7.5 GHz center frequency and 2 zeros at 12.5 GHz and 15 GHz.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
